How to remove the background on all elements on the page on button click?

Question

css

There is a version of the site for the visually impaired. How to remove the background in all elements on the page on button click?

Answer 1

Yes, just when you click on the button, hang a class on the body

.no-bg, .no-bg * {
background: none
}

It is better, of course, to remove specific elements, rather than using *. But for this you need to know them or search through js.
And do not forget that the icons on the site are often made using bg.

Answer 2

If you need to remove all of them, then you can. And if necessary, return background to certain elements.
