What is the best way to retinize images?

Question

css

Who does retination and why?
I want to find a better way, because previously I stupidly squeezed the block 2 times less.
Heard about src set , but only heard :)
Thanks.

Very good and detailed article. You will understand what is written here, you can even wipe your nose at an experienced front-end developer in some dispute =)

Answer 2

<picture class="intro-background">
  <source srcset="images/[email protected]" media="(min-width: 2521px)">
  <source srcset="images/[email protected]" media="(min-width: 1261px)">
  <img src="images/background.png">
</picture>

Better than any words.
