Is there any way to set different formats for images in background?

Question

css

Hello, tell me if, for example, for markup, you can go the way picture and soure set in several image formats, just in case, figuratively png and webp.
How to solve the issue with an image that is set in css, options, or take the risk that webp is suddenly not supported by a person, or implement all this through markup, stretching the image to the background through positioning?

Answer 1

<picture>
                <source srcset="picture.webp">
                <source srcset="picture.png">
</picture>
