On what sites and for what purpose can I apply the slider BEFORE and AFTER?

Question

Browsers

This refers to the subject of sites or examples
. For example, photo studios, apartment renovations, etc.

Answer 1

Any site where there is a "before and after" logic.
For example, "before a broken nose | after" (plastic surgery site), or
"Stupid question | an example of restyling a question after realizing its stupidity" (a site for collecting stupid questions from a toaster)
