1. HTML ‘srcset’ and ‘sizes’ Attributes

The srcset and sizes properties were added to HTML5 to allow for the specification of multiple image sources and their corresponding sizes. This enables the browser to choose the ideal image based on the user’s device and screen size.

<img src="image-small.jpg"
     srcset="image-small.jpg 300w,
             image-medium.jpg 600w,
             image-large.jpg 1200w"
     sizes="(max-width: 600px) 100vw, 50vw"
     alt="Responsive Image Example">

In this example, the user will get the best experience possible because the browser selected the best image depending on the screen width and device capabilities.

2. CSS ‘max-width’ and ‘background-image’

For images to scale appropriately with the viewport, you can use CSS to establish a maximum width. The background-image attribute can also be used for dynamic background images.

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

.header {
  background-image: url('header-image.jpg');
  background-size: cover;
  background-position: center center;

This approach allows for flexible images and background images that adapt to different screen sizes without distorting or cropping.

3. Picture Element

In HTML5 tag is used in choosing and adding responsive images inside the website. You can specify different image sources and media conditions within the element.

  <source srcset="image-small.jpg" media="(max-width: 600px)">
  <source srcset="image-medium.jpg" media="(max-width: 1200px)">
  <img src="image-large.jpg" alt="Responsive Image Example">

Using this tag we can change the size of the image according to the different screen sizre by specifying the size insid the picture element.

4. Javascript Solutions

JavaScript libraries and frameworks like Lazysizes and Imgix offer advanced features for responsive images. These tools can automatically handle lazy loading, image resizing, and optimization.

  data-srcset="image-small.jpg 300w,
               image-medium.jpg 600w,
               image-large.jpg 1200w"
  alt="Responsive Image Example">

For a seamless user experience and to improve page performance, your website’s responsive image strategy must be chosen carefully. Your individual needs and the degree of control you require over image selection will determine the approach you choose.

When it comes to responsive photos, employing the HTML srcset and sizes properties is typically a wise decision because it strikes a nice mix between simplicity and control. The additional methods discussed here, such as CSS-based solutions, the picture> element, or JavaScript libraries, may be advantageous in more complicated cases.
