How to know where to use css, less and Sass?


Staff member
I have knowledge of HTML, CSS, and jQuery. Recently I knew about <a href="" rel="nofollow noreferrer">Sass</a> and <a href="" rel="nofollow noreferrer">less</a>. As they both are the style sheet language I am a little bit confused about where to use both of them as CSS is already there and it is also widely used in every website. So how to know where to use these (Less, Sass) in that particular field.

Another doubt comes to my mind is, is it fine to use Sass and Less in <a href="" rel="nofollow noreferrer">wordpress</a> instead of default CSS?
