Is it possible to remove blocks through conditions in the sass preprocessor?

Question

css

For example, I have some page with two div blocks one after the other in a line, the page width is 1000px, is it possible to set a condition in the preprocessor so that when the window width changes (narrowing) one of the blocks disappears?
Or is it only through js?

Answer 1

are used for this

@media

requests
preprocessors - this is a CSS preprocessor, the browser understands CSS, not LESS/SASS
