Mobile-first approach with HTML and CSS

Farhad Rahmani — Sat, 08 Jul 2023 09:04:47 +0000

In today’s digital landscape, the mobile-first approach has gained significant importance in web design and development. By adopting a mobile-first approach with HTML and CSS, you prioritize the needs of mobile users and ensure your website delivers a seamless and engaging experience on small screens. This article will explain the principles and benefits of mobile-first design and implementing specific strategies with HTML and CSS so you can apply the methodology.

The mobile-first approach is a design and development approach focusing on creating a user-friendly experience for mobile devices like smartphones and tablets. Unlike the traditional method of starting with desktop design and adapting it for mobile, the mobile-first approach begins with designing specifically for mobile devices and then expanding to larger screens. This approach ensures that the needs of mobile users are prioritized, considering the widespread usage of mobile devices in today’s digital world. It is an excellent approach to creating a responsive design.

The mobile-first approach is essential for several reasons:

It ensures developers prioritize performance optimization, resulting in faster load times, reduced data usage, and a smoother experience for mobile users.
It enables websites and applications to adapt and scale quickly across different devices and screen sizes.
Users can seamlessly navigate and engage with the mobile interface, increasing user satisfaction and engagement.
It helps businesses to effectively target and engage with their audience, ensuring seamless experience and interaction.
It enables you to concentrate on delivering clear and concise content.
It can improve your search engine visibility and drive more organic traffic to your site.

Fundamental principles of the mobile-first approach

Several principles can help shape the design and development process of the mobile-first approach. They include:

The mobile-first approach involves designing for the smallest screen and working your way up. Focusing on mobile users first is essential to carefully tailor the user experience to optimize smaller screens and accommodate touch-based interactions.
Identify core elements mobile users need to create an efficient, clutter-free experience. For example, prioritize straightforward navigation, user-friendly forms, responsive media, mobile-specific interactions, and prominent call-to-action buttons as core elements for mobile users.
Optimize performance by minimizing file sizes and employing techniques like lazy loading to enhance speed and responsiveness.
Implement responsive design techniques to ensure your website or application adapt seamlessly to different screen sizes and devices.
Designing intuitive touch-based interfaces is a fundamental aspect of the mobile-first approach, leveraging natural gestures like tapping, swiping, and pinching to enhance user-friendliness.
Begin with a solid foundation for the mobile experience and then enhance it for larger screens and more powerful devices. This approach allows you to add extra features and optimize the design for desktop users without compromising the core mobile experience.

Structuring HTML

You can effectively implement a mobile-first approach with HTML and CSS, ensuring a responsive and user-friendly design for mobile devices while accommodating larger screens and providing a seamless cross-device experience. Structuring HTML is an essential aspect of building a mobile-first approach. Here are ways to do that better:

Start with a well-organized HTML structure, including the doctype declaration (<!DOCTYPE html>) and semantic elements like <html>, <head>, and <body>.
Utilize semantic HTML tags for effective content structure, such as using <h1> to <h6> for headings based on hierarchy, <nav> for navigation menus, <article> for self-contained content, and <section> for grouping related content.
Enhance the mobile user experience by incorporating mobile-friendly elements like <input type="tel"> for telephone numbers, <input type="email"> for email addresses, and <input type="date"> for date inputs. These elements facilitate appropriate keyboard layouts and input options.
Create a mobile-friendly navigation structure for smaller screens, utilizing techniques like a collapsible menu (<button> with associated <ul> or <nav>), a hamburger icon, or a slide-out panel to ensure easy usability and accessibility.
Include accessibility features in your HTML structure, such as alt attributes for images (<img>) and proper labeling for form inputs (<label>), to enhance navigation and understanding of your content for users with disabilities.
Improve code readability and navigation by maintaining consistent indentation and using whitespace effectively to enhance the structure and readability of your HTML.

Let’s see an example of how to structure the HTML:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>My Mobile-First Approach</title>
  </head>
  <body>
    <header>
      <h1>My Mobile-First Approach HTML Structuring</h1>

      <nav>
        <a href="">Home</a>
        <a href="">Shop</a>
        <a href="">Contact</a>
        <a href="">Store</a>
      </nav>
    </header>

    <main>
      <section>
        <h2>About Us</h2>
        <p>
          We work with skilled artisans and select premium materials to craft
          footwear that stands the test of time
        </p>
      </section>

      <section>
        <h2>Our Products</h2>
        <ul>
          <li>Men's shoes</li>
          <li>Women's Shoes</li>
          <li>Kid's Shoes</li>
        </ul>
      </section>

      <section>
        <h2>Contact Us</h2>
        <form>
          <label for="name">Name:</label>
          <input type="text" id="name" name="name" />

          <label for="email">Email:</label>
          <input type="email" id="email" name="email" />

          <label for="message">Message:</label>
          <textarea id="message" name="message"></textarea>

          <input type="submit" value="Send Message" />
        </form>
      </section>
    </main>

    <footer>
      <p>&copy; 2023 My Mobile-First Approach Example. All rights reserved.</p>
    </footer>
  </body>
</html>

The outcome:

The example above follows the mobile-first approach and includes the necessary structure for a website. It sets the document type, defines the viewport for responsive behavior, and consists of a title for the page. It also comprises a header, a main content area with sections, and a footer. The navigation bar, sections, and form are organized using semantic HTML tags.

Creating responsive grid systems

By leveraging the power of CSS Flexbox and CSS Grid, you can create versatile and responsive grid systems that adapt gracefully to different devices, providing an optimal user experience for mobile and desktop users. Here is how you can use CSS flexbox and grid to create a responsive grid system for the mobile-first approach:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My Mobile-First Approach</title>
    <style>
      .grid-container-flex {
        display: flex;
        flex-direction: column;
        background-color: purple;
        font-size: 1.5rem;
        color: white;
        margin-top: 1rem;
        height: 7em;
      }

      .grid-container-grid {
        display: grid;
        grid-template-columns: 20em;
        height: 8em;
        font-size: 1.1rem;
      }
    </style>
  </head>
  <body>
    <header>
      <h1>My Mobile-First Approach HTML Structuring</h1>
      <nav>
        <a href="">Home</a>
        <a href="">Shop</a>
        <a href="">Contact</a>
        <a href="">Store</a>
      </nav>
    </header>

    <main>
      <section class="grid-container-flex">
        <h2>About Us</h2>
        <p>We work with skilled artisans and select premium materials to craft footwear that stands the test of time</p>
      </section>

      <section class="grid-container-grid">
        <h2>Our Products</h2>
        <ul>
          <li>Men's shoes</li>
          <li>Women's Shoes</li>
          <li>Kid's Shoes</li>
        </ul>
      </section>

      <section>
        <h2>Contact Us</h2>
        <form>
          <label for="name">Name:</label>
          <input type="text" id="name" name="name">

          <label for="email">Email:</label>
          <input type="email" id="email" name="email">

          <label for="message">Message:</label>
          <textarea id="message" name="message"></textarea>

          <input type="submit" value="Send Message">
        </form>
      </section>
    </main>

    <footer>
      <p>&copy; 2023 My Mobile-First Approach Example. All rights reserved.</p>
    </footer>
  </body>
</html>

The outcome:

The Flexbox layout is applied to the “About Us” section in the above example, arranging its elements in a vertical column. The Grid layout is used for the “Our Products” section, organizing its elements in a single column. These CSS techniques help create responsive and adaptable layouts that can be customized and optimized for different devices and screen sizes.

You can check out CSS Flexbox and CSS Grid for in-depth knowledge of how to use them and create a responsive grid system for the mobile-first approach.

Responsive Design with CSS Media Queries

Implementing responsive design with CSS media queries enables you to apply different styles based on the device’s screen size. This approach is commonly used with the mobile-first approach to improve user experience across various devices.

You can create a responsive design using CSS media queries that provides an optimal viewing experience across multiple devices. It allows you to tailor your styles to different screen sizes’ specific needs and constraints, ensuring that your website or application is user-friendly and visually appealing on all devices.

Here is how you can use CSS media queries for a mobile-first approach:

Design and style your mobile device website or application using CSS rules targeting smaller screens. This enables your design optimization for mobile users and establishes the mobile-first foundation.
You will use the min-width media query for the mobile-first approach to enhance the design as the screen size increases progressively. This means that the default styles will be for mobile, and additional styles will be added as the screen size increases.
You must determine the breakpoints at which you want to introduce layout or styling changes. Breakpoints are specific screen widths at which your design will adapt to fit the screen size better. Standard breakpoints include tablets, desktops, and larger screens.
To target specific screen sizes, write media queries using the @media rule and the min-width property.

For example:

<!DOCTYPE html>
<html>
 <head>
   <meta charset="UTF-8">
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <title>My Mobile-First Approach</title>
   <style>
     /* Default styles for mobile */
     .grid-container-flex {
       display: flex;
       flex-direction: column;
       background-color: purple;
       font-size: 0.9rem;
       color: white;
       margin-top: 1rem;
       height: 9em;
     }

     .grid-container-grid {
       display: grid;
       grid-template-columns: 20em;
       height: 8em;
       font-size: 1.1rem;
     }

     /* Media query for tablets */
     @media (min-width: 768px) {
       .grid-container-flex {
         font-size: 1.3rem;
       }

       .grid-container-grid {
         grid-template-columns: none;
         height: 10em;
       }
     }

     /* Media query for desktops */
     @media (min-width: 1024px) {
       .grid-container-flex {
         font-size: 2rem;
       }

       .grid-container-grid {
         grid-template-columns: none;
         height: 12em;
       }
     }
   </style>
 </head>
 <body>
   <header>
     <h1>My Mobile-First Approach HTML Structuring</h1>
     <nav>
       <a href="">Home</a>
       <a href="">Shop</a>
       <a href="">Contact</a>
       <a href="">Store</a>
     </nav>
   </header>

   <main>
     <section class="grid-container-flex">
       <h2>About Us</h2>
       <p>We work with skilled artisans and select premium materials to craft footwear that stands the test of time</p>
     </section>

     <section class="grid-container-grid">
       <h2>Our Products</h2>
       <ul>
         <li>Men's shoes</li>
         <li>Women's Shoes</li>
         <li>Kid's Shoes</li>
       </ul>
     </section>

     <section>
       <h2>Contact Us</h2>
       <form>
         <label for="name">Name:</label>
         <input type="text" id="name" name="name">

         <label for="email">Email:</label>
         <input type="email" id="email" name="email">

         <label for="message">Message:</label>
         <textarea id="message" name="message"></textarea>

</html>

The above example includes CSS media queries for a mobile-first approach to adjust the styles for different screen sizes. The mobile styles are applied by default, and certain elements’ font size and height are increased for tablets. The font size and height are further adjusted for desktops to ensure optimal display on larger screens.

You can check out CSS media queries for an in-depth understanding of using CSS media queries.

Testing and Optimization

Testing and optimization are crucial steps in the mobile-first approach to ensure the effectiveness and performance of the designed website or application on various mobile devices.

In the developer tools, you can use responsive design testing tools in modern browsers, such as Chrome’s Device Mode, to test on various devices and screen sizes. These tools allow you to simulate multiple devices and screen sizes, visually representing how the code renders on different devices.

Let’s check how the mobile-first approach is displayed on different devices.

Mobile display: )

Large screen display:

Tablet display:

Using responsive image techniques

Responsive image techniques for the mobile-first approach allow the images to adjust to different screen sizes, ensuring a better user experience on mobile devices while still providing high-quality images on larger screens.

Some of the techniques to use when implementing responsive image techniques for a mobile-first approach include:

the picture element can present different images based on screen size. For example:

<picture>
  <source media="(min-width: 768px)" srcset="large.jpg">
  <source media="(min-width: 480px)" srcset="medium.jpg">
  <img src="small.jpg" alt="Responsive image">
</picture>

The above example enables the browser to choose large.jpg for screens wider than 768 pixels, medium.jpg for screens wider than 480 pixels, and fallback to small.jpg for smaller screens.

To avoid overflow of images from the container on different screen sizes, set the max-width property of the image to 100% and let the height scale automatically to maintain the image’s aspect ratio.

For example:

img {
  max-width: 100%;
  height: auto;
}

To set multiple image sources with different resolutions or sizes, use the srcset attribute. This enables the browser to select the most appropriate image based on the device’s screen size and pixel density.

Example:

<img src="small.jpg" srcset="medium.jpg 800w, large.jpg 1200w" alt="Responsive Image">

The above example shows the browser will choose between small.jpg, medium.jpg, or large.jpg based on the available width (800w or 1200w).

Conclusion

The mobile-first approach prioritizes mobile users and eliminates the issues associated with scaling down from desktop to mobile. By following the mobile-first approach and incorporating responsive design principles, we can create flexible and adaptive websites that meet the diverse needs of users across different screen sizes and devices. We can create a user-centered and efficient design that works well on mobile devices by starting with the smallest screens and focusing on essential content and functionality.

How to Use GitHub Copilot to Become More Productive Developer

Farhad Rahmani — Thu, 06 Jul 2023 09:06:47 +0000

There are a number of AI tools for developers emerging on the market. But in my mind GitHub Copilot stands above the rest because of its usability, seamless IDE integration, and remarkable enhancements to developer productivity.

Copilot offers a variety of AI tools that have radically streamlined my experience as a software developer. I've used it to generate code, tests, and even simple applications. It's also great for debugging, refactoring, and documenting existing code.

Weirdly, using Copilot has caused me to develop features faster than business stakeholders can review them.

It's important to note that AI tools, including Copilot, can be blatantly wrong, apologize (or not) when corrected, and then confidently produce the same error. But as long as you're aware of the downsides of AI tools, and have enough coding knowledge to recognize when they're incorrect, you can mitigate them on the path to substantially improved productivity.

How to Setup GitHub Copilot

For setup and basic usage of Copilot, check out the docs. You can add on Copilot to an individual or business account, and there's a free trial and reasonable pricing after the trial.

After adding Copilot to your GitHub account, you'll want to install the plugins for your IDE and log into GitHub to access Copilot.

In this article, we'll use these Visual Studio Code extensions:

GitHub Extension	Description	Preview
Copilot	AI pair programmer with in-IDE code suggestions	No
Copilot Nightly	Nightly build of Copilot, includes latest changes	No
Copilot Labs	Experimental features in sidebar	Yes
Copilot Chat	Interactive chat in sidebar, part of Copilot X	Yes
Copilot Voice	Voice assistant	Yes

Notes:

This info is up-to-date as the writing of this article, but will likely change as GitHub evolves these products.
I haven't yet received access to Copilot Voice or Copilot (X) for Pull Requests, so my perspective on these are limited and based on GitHub's preview docs.

Privacy

Before jumping into some key use cases for Copilot, a quick note on privacy: Basically, if you trust GitHub to host your source code, you can likely trust what they do with your Copilot prompts and code snippets. [See their FAQ docs and Privacy Statement.]

Use Cases for GitHub Copilot

The uses cases for GitHub Copilot are numerous, especially when you add in the preview features of Labs, Chat, and Voice. Using Copilot's features can really streamline the development process.

Here are some great ways to leverage Copilot extensions:

Category	Extension(s)
Code Generation	Copilot, Copilot Nightly, Copilot Voice
Explaining Code	Copilot Labs, Copilot Chat, Copilot Voice
Language Translation	Copilot Labs, Copilot Chat
Debugging	Copilot Labs, Copilot Chat
Refactoring	Copilot Labs, Copilot Chat
Test Generation	Copilot, Copilot Nightly, Copilot Labs, Copilot Chat
Code Reviews	Copilot Chat
Voice-Driven Development	Copilot Voice

Code Generation

Copilot is known for its code completion features. If it's given a comment in the code or you type the beginnings of a line of code, Copilot will suggest a solution that you can accept, ignore, or explore alternatives. It's referred to as "ghost text".

Once you have the Copilot extension installed and you're logged in, code completion is as simple as typing instructions and hitting the Tab key once the suggestion comes up.

A comment prompt in Ruby that Copilot uses to create a method and invocation

Taking code completion one step further, Copilot Chat can take a single prompt and generate instructions for building an entire application.

I asked it to create a REST API in Node with CRUD functions for "products", and it generated functional code. Impressive overall. Given the same prompt, ChatGPT also gave me instructions for how to run the code, which was nice.

Copilot Voice can also write or edit code based on voice commands. Most of the time, using the keyboard with Copilot code completion is faster than dictating lines of code with Voice. But it's compelling to think about using Copilot Voice to create and run code without having to type or stare at a screen.

Explaining Code

I often have to stare at a screen to figure out what a block of code is doing. Sometimes it's legacy code where I don't understand the business context. Sometimes it's using a particular library I'm not used to. Sometimes I curse the person who wrote it, even if it's me.

Below is some code generated by Copilot Chat from my "REST API in Node..." prompt from above:

app.get('/products/:id', (req, res) => {
  const id = req.params.id;
  const product = products.find((p) => p.id === id);
  if (product) {
    res.json(product);
  } else {
    res.status(404).json({ error: 'Product not found' });
  }
});

I took this code and fed it into the "Explain" feature in Copilot Labs. Here's the response...

Here is the explanation for the code above:

We define a route with the route path /products/:id. The colon : in the path indicates that it is a route parameter. The value of the route parameter will be available in req.params. For example, if the route path is /products/:id and we make a request to /products/5, then the value of req.params will be { id: 5 }.
We get the id from req.params and find the product with the given id from the products array. If a product with the given id exists, we return it. Otherwise, we send a 404 error response with the error message Product not found.

This is a pretty straightforward segment of code, and the response is clear and straightforward as well. It would be easy to add this as documentation in a code comment above the function.

Another good example is regular expressions. I understand how regular expressions work but I don't often have the patience to figure out what a particular regex is doing. I fed Copilot Chat this giant regex statement for email validation:

(?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*|"(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*")@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\[(?:(?:(2(5[0-5]|[0-4][0-9])|1[0-9][0-9]|[1-9]?[0-9]))\.){3}(?:(2(5[0-5]|[0-4][0-9])|1[0-9][0-9]|[1-9]?[0-9])|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\])

It explained the regex at a high level, indicating it was broken into the local and domain parts, representing before and after the "@" sign in an email address. Then it described allowable characters in each part. Quite helpful.

Language Translation

Developers are often required to quickly learn new languages and frameworks. Copilot Labs and Chat make this pretty easy. Here's an array of products in JavaScript and Ruby that was converted by Copilot:

let products = [
  { id: '1', name: 'Product 1', price: 10.99 },
  { id: '2', name: 'Product 2', price: 19.99 },
  { id: '3', name: 'Product 3', price: 7.99 }
];

products = [
  { id: '1', name: 'Product 1', price: 10.99 },
  { id: '2', name: 'Product 2', price: 19.99 },
  { id: '3', name: 'Product 3', price: 7.99 }
]

This is a very simple example, so let's try making this into a class and going the other way (from Ruby to JavaScript):

class Product
  attr_reader :name, :price

  def initialize(name, price)
    @name = name
    @price = price
  end
end

class Product {
  constructor(name, price) {
    this.name = name;
    this.price = price;
  }
}

This checks out. For good measure, I tested TypeScript as well, and it worked perfectly, too.

Debugging

This is a very handy feature. You can give Copilot Chat or Labs problematic code or error messages and it will indicate what it thinks the issue is.

Copilot Labs "Fix Bug" Brush Feature

I can't tell you how many hairs I've pulled out because I couldn't find what amounted to a syntax error. Copilot's ability to fix bugs just makes me happier and hairier.

You can also give Copilot Chat an error message with no other prompt and it can tell you the issue. I arbitrarily removed a dot from the Node REST API code:

products[productIndex] = { id, ..req.body };

I copied/pasted the error message in Chat, and it responded with...

Looking at the code excerpt you provided, it seems that the issue is on line 49 where there is a syntax error in the object literal. The ".." before req.body is causing the error. It should be just one dot instead of two.

This is both correct (the line and source of the error) and incorrect (that it should be only one dot). It then gave me a code snippet with three dots, which is also correct.

As I mentioned at the outset, you've gotta double-check AI's work. Still, I'm impressed by Copilot's ability to parse an error message, describe what it thinks is wrong, and suggest a fix.

Refactoring

Another great use case is refactoring. Consider the code below:

def price_with_discount
  price - (price * discount_rate)
end

This simple price calculation doesn't factor in nil values, strings that should be numbers, or reasonable values for price or discount_rate. We need the code to do this:

Ensure price is an integer or float (not nil)
Ensure price is not negative
Ensure discount_rate is a float (not nil)
Ensure discount_rate is not negative and less than or equal to 1

Copilot Chat handles this with ease...

def price_with_discount(price, discount_rate)
  raise ArgumentError, "Price must be a positive number" unless price.is_a?(Numeric) && price >= 0
  raise ArgumentError, "Discount rate must be a float between 0 and 1" unless discount_rate.is_a?(Float) && discount_rate >= 0 && discount_rate <= 1

  price - (price * discount_rate)
end

Test Generation

Using Copilot to generate tests is technically a subset of "Code Generation" above, but I felt it was so useful it warranted its own mention.

Generating unit tests for code can be tedious if you're trying to cover happy and sad paths, primary use cases and edge cases. Our price_with_discount code above needs test cases to ensure an error is raised if price or discount_rate don't meet the requirements. In addition, we might want to test the following:

A price without a discount_rate
A price with a reasonable discount_rate (for example, a 10% discount)
A price with a 100% discount_rate (for example, if we want to give the product away)

With these and our previous error cases, here's what Copilot Chat generated, after a little fine-tuning (re-prompting) and switching from Minitest to Rspec.

RSpec.describe Product do
  describe "#price_with_discount" do
    context "when given a valid price and discount rate" do
      it "returns the price with the discount applied" do
        product = Product.new("Test Product", 100, 0.2)
        expect(product.price_with_discount(product.price, product.discount_rate)).to eq(80)
      end
    end

    context "when given a nil price" do
      it "raises an ArgumentError with an appropriate message" do
        product = Product.new("Test Product", nil, 0.2)
        expect { product.price_with_discount(product.price, product.discount_rate) }.to raise_error(ArgumentError, "Price must be a positive number")
      end
    end

    context "when given a price less than 0" do
      it "raises an ArgumentError with an appropriate message" do
        product = Product.new("Test Product", -100, 0.2)
        expect { product.price_with_discount(product.price, product.discount_rate) }.to raise_error(ArgumentError, "Price must be a positive number")
      end
    end

    context "when given a nil discount rate" do
      it "raises an ArgumentError with an appropriate message" do
        product = Product.new("Test Product", 100, nil)
        expect { product.price_with_discount(product.price, product.discount_rate) }.to raise_error(ArgumentError, "Discount rate must be a float between 0 and 1")
      end
    end

    context "when given a discount rate less than 0" do
      it "raises an ArgumentError with an appropriate message" do
        product = Product.new("Test Product", 100, -0.2)
        expect { product.price_with_discount(product.price, product.discount_rate) }.to raise_error(ArgumentError, "Discount rate must be a float between 0 and 1")
      end
    end

    context "when given a discount rate greater than 1" do
      it "raises an ArgumentError with an appropriate message" do
        product = Product.new("Test Product", 100, 1.5)
        expect { product.price_with_discount(product.price, product.discount_rate) }.to raise_error(ArgumentError, "Discount rate must be a float between 0 and 1")
      end
    end
  end
end

One test for valid input, five for invalid input. All six work, and I didn't have to write them!
