Sass is a meta-language on top of CSS. Installation: Sass is part of Haml, which is available via git.
gem install haml
Sass can be used with Ruby, Ruby on Rails or as a command-line tool. To run Sass from the command line
sass input.sass output.css
Sample Usage (with variables)
// constants !main_color = blue !site_background = white body :color = !main_color :font :family verdana, arial, sans-serif :size 12px
Sass can calculate
!color2 = !main_color*0.33 + !site_background*0.67 !color3 = !main_color*0.67 + !site_background*0.33 #box :color = !color2 :background_color = !color3
Remarks: - Sass bzw. Haml Homepage: http://haml.hamptoncatlin.com/ - Sass and CSS cannot be mixed. Existing CSS has to be translated to Sass first. The commandline tool "css2sass" can help.
