What’s the difference between Less and Sass?

Question

What is the difference of each and advantages and disadvantages?

Answer 1

There is a Gist in which differences and specifics are put into detail.

There is also this document where several more macro aspects are weighed between the two standards, that in the final evaluation the SASS is superior, although the LESS has several things in its favor. I recommend also read the part of the comments.

There is even a pattern called Stylus, very succinct and beautiful, but with little adherence until then, but that deserves attention.

In the most, there are at least 8 CSS preprocessors, known and semi-known, summarized here. Worth a quick read.

Anyway, it’s important to say that the choice should also be based on the amount of tools available to pre-process CSS in your favorite technology. For example, Bootstrap and web2py have their style sheets made in LESS. Yeoman has a more developed support for SASS, and so on.
