LESS, CSS, Bootstrap, SASS Comparison

Hi,

i have been doing some reading about the new css techniques such as bootstrap, LESS, and SASS. every article i come across either boasts about the new technique or says its not worth while. so i have two questions :
1. what are the difference between them
2. what are the benefits of using them

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

AFAIK, bootstrap is a CSS/JS library/framework used to create responsive layouts. Initially created at and for twitter, it's now probably the most popular framework for building mobile-ready sites.

SASS is a scripting language that produces CSS. What that means is that you write code in SASS (which is supposedly faster/better) and the interpreter will output CSS code.

LESS is another scripting language that produces CSS. It is the language bootstrap was written in.
Or, it could refer to the LESS framework, which is a css library with a pre-built grid system.

Benefits of using SASS or LESS: if you're a programmer, you can write css code with familiar constructs. If not, you can at least keep your code better organized and output production-ready css without comments and clutter.

HTH,
Dan
