Module 10: Responsive Web Design with HTML

Responsive web design is crucial for providing an optimal user experience across various devices. Here are some practical tips and examples for implementing responsive design:

  1. Viewport meta tag: Ensure that every HTML document includes the viewport meta tag to control the page's dimensions and scaling on different devices. Without it, mobile browsers may render pages at a default desktop width, leading to poor user experiences.
  2. Media queries: Use media queries to apply different styles based on screen size, resolution, and other device characteristics. For example, you can define specific CSS rules for small screens (e.g., smartphones), medium screens (e.g., tablets), and large screens (e.g., desktops).
  3. Responsive images: Optimize images for various screen sizes and resolutions using the srcset and sizes attributes. This allows browsers to choose the most appropriate image based on the user's device, improving performance and reducing bandwidth usage.

Example 1: Viewport Meta Tag

Include the following viewport meta tag in the <head> section of your HTML document:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Example 2: Media Queries

Apply different styles for small screens using media queries:

@media screen and (max-width: 600px) {
  /* Styles for small screens */
}

Example 3: Responsive Images

Use the srcset attribute to specify multiple image sources:

<img src="image.jpg" srcset="image-400.jpg 400w, image-800.jpg 800w, image-1200.jpg 1200w" alt="Responsive Image">
