LESS vs SASS Quick Tutorial

If you don't have an understanding about LESS and SASS then focus on this article I will share every important point especially for beginners. You have to just concentrate on your reading.

LESS and CSS both are a CSS Preprocessor, a scripting language extends CSS into variable and compiles as normal CSS. The overall reason behind LESS and SASS is to save developers time to write lot's of styling tags and HEX color values. Saving developers time and minimize the number of lines for repeated styling content.

SASS vs LESS complete tutorial


Don't go through the name may be it looks like same but they have lot's of differences as below:

1- LESS is JavaScript based preprocess and Sass is Ruby based

2- They have different extension .less and .scss

3- In SASS you can use  Compass and for LESS use mixin libraries like battling to be the best.

4- Installation for LESS is quite easy in compare to SASS because it has only JS dependencies.

5- SASS trends to more logical and functional area with more usable components pattern.

If you are new for both of preprocessor's CSS then I suggest you to start with SASS, in the installation SASS may become trouble for you but once you were done, you must love to code in SASS.


How to Install SASS using Command Line ?

Example for SASS and LESS:


$font-face: Segoe UI, sans-serif;
$main-color: #000;

body {
 font: 100% $font-face;
 color: $main-color;

$font-face and $main-color are two variable here, we have to define property once and after that, we can reuse.

Extend: Most powerful feature in SASS and LESS, you can reuse class components in SASS using @extend keyword.

.msg {
 border: 1px solid #00;
 color: #333

.scs {
 @extend .msg;
 border-color: red;


@font-face: Segoe UI, sans-serif;
@main-color: #000;

body {
 font: 100% @font-face;
 color: @main-color;

@font-face and @main-color , there are two variable with @ selector.

Extend: As above you can use extend in LESS using :extend keywords.

.msg {
 border: 1px solid #00;
 color: #333
