There’s always a debate about who is better in every community. People debate about DC and Marvel, Coca-Cola, and Pepsi, and you have a Mac and PC in computing.
For web developers/designers, that debate is Sass or Less.
What Are Sass and LESS?
Syntactically Awesome Stylesheets (Sass) and Leaner CSS (LESS) are both CSS preprocessors.
A CSS preprocessor is a program that lets you generate CSS from the preprocessor’s unique syntax.
There are many CSS preprocessors to choose from. However, most CSS preprocessors will add features that don’t exist in pure CSS, such as mixing, nesting selectors, inheritance selectors, etc.
If you plan on taking advantage of the web world, having an idea in one of the two pre-processors or both is great.
Both are similar in essence. They make writing CSS simpler, more object-oriented, and more enjoyable.
Nevertheless, with every similarity comes a difference. Five of them are listed here.
LESS Has More User-Friendly Documentation Than Sass
The LESS documentation is visually appealing and easier for first-time users to follow. The Sass documentation has much more of a knowledge base or wiki setup.
This fact could be important to the adoption rates of either Sass or LESS since Sass is a platform designed for website design.
Sass Is in Ruby. LESS Is in JavaScript
Sass is based on Ruby and requires a Ruby install. This is no big deal if you have a Mac.
However, it takes longer to install on a Windows machine. LESS was constructed in Ruby, like Sass, but it has been ported to JavaScript.
To use LESS, you upload the applicable JavaScript files to your server or compile the CSS sheets using an offline compiler.
LESS Has Better Error Messages Than Sass
Sass and LESS have been tested for their ability to report syntax errors. LESS has more accurate error messages in the tests in that it reports the correct location of the error
Something like this could save a bit of time sweating over a typo.
Sass Has Compass, LESS Has Preboot
Sass and LESS have extensions to integrate mixins (the ability to store and share CSS declarations throughout a site).
- Sass has Compass available for mixins, including every available option and updates for future support.
- LESS has Preboot.less, LESS Mixins, LESS Elements, gs, and Frameless. LESS’s software support is more fragmented than Sass, resulting in many different options for extensions that may not all function the same way. For your project, you may need all of the listed extensions to get a similar performance to Compass.
To Assign Variables: Sass Uses $; LESS Uses @
Both Sass and LESS use specialized characters to assign variables. This way, you don’t have to keep entering specifications; you can enter the character.
In Sass, it’s the dollar sign ($). In LESS, it’s the at symbol (@). The only downside for LESS is that a few existing CSS selectors already use @, so it may slightly stiffen the learning curve.
Now that I have explained the difference between these two CSS preprocessors, it’s up to you to choose which one is easier to work with.
