What is Sass?
To quote the official Sass website:
Sass makes CSS fun again. Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It’s translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.
So Sass is a great way of writing a more terse and functional way of writing CSS. Of course the Web Workbench does away with the need to use a command line tool or web-framework plugin as you write Sass, we'll generate the CSS when you save!
The Mindscape Web Workbench includes all the requirements you need to start writing Sass in Visual Studio. Simply follow our getting started guide and you'll be up and running in no time. Sass is nice and easy to get started with and you'll be saving time while creating amazing styles in no time!
