Step 1

A responsive image means an image which fits automatically to its screen size.

Multiple ways are there to implement responsive images:

Method-1:

Using responsive class in image tag,

<img src="xxx.jpg" alt="alt_name" class="responsive">

In image tag, set Class attribute to "responsive". 

Method-2:

  • Using the srcset, sizes, and media attributes in the image tag,
  • srcset attribute used to the width of the image along with image file source.
  • sizes attribute to specify the size of the image related to its viewport through media condition.
  • Media attribute used to define media condition.

<img src="xxx.jpg" srcset="src width" sizes="" alt="alt_name" c>
