LESS & Sass

The two most popular supersets of CSS are fully supported. The support covers everything the CSS editor offers plus some additional features.


Quickly access your variables from the current document or any imported files. The tooltip shows the value of each variable so you don't have to guess.

LESS variables


The editor provides both IntelliSense and tooltips for Mixins in the same file as well as across imported files.

LESS mixins

Go to definition

Easily jump between Mixins and variable references using F12 to go to the definition. This works for any references, even across multiple files and imports.
