How it works

<img src="path/to/image.png" srcset="2x, 3x" alt="Text representation of image.">
<img src="path/to/image@2x.png" alt="Text representation of image.">
 
<img src="path/to/image-320w.png" sizes="100vw" srcset="320w, 640w, 980w" alt="Text representation of image.">
 
<picture>
  <source src="path/to/filename-large.png" media="(min-width: 1000px)" srcset="1x, 2x, 3x">
  <source src="path/to/filename-medium.png" media="(min-width: 800px)" srcset="1x, 2x, 3x">
  <img src="path/to/filename-small.png" srcset="1x, 2x, 3x" alt="Text representation of image.">
</picture>

<picture>
  <source media="(min-width: 1000px)" srcset="path/to/filename-large.png,path/to/filename-large@2x.png 2x,path/to/filename-large@3x.png 3x">
  <source media="(min-width: 800px)" srcset="path/to/filename-medium.png,path/to/filename-medium@2x.png 2x,path/to/filename-medium@3x.png 3x">
