I started using Less for a project at work. I really liked it: variables, nested CSS all very cool. One Downside. The Editor we use ,PHP Designer 7, doesn’t support Syntax Highlighting out of the box for LESS.
But I found an easy fix today. In the preferences on the Tab for the File association, just add .less as a file type do CSS and PHP designer adds syntax Highlighting to less files. Easy as pie.
PHP Designer has some hick ups with nested CSS but it works.
