KSS

SMACSS

Gulp ...

  • is a command line tool for frontend preprocessing
  • enables live editing with multiple devices using browser sync
  • let you generate a Styleguide with KSS-Node

Gulp example

SASS ...

  • is a CSS preprocessor
    • enables you to organize your (S)CSS code in multiple files
    • makes it easy to use coding standards like SMACSS and BEM
  • Lib-Sass
    • libsass is "up to 4000% faster!"*
    • use it for new projects

Syntactically Awesome StyleSheets

SASS EXAMPLE

Singularity Grid

  • the grid system I know (using Omega4)
    http://singularity.gs
  • workes with libsass
  • depends on breakpoint
    http://breakpoint-sass.com
  • just use your favorite grid system, but make sure it will run with libsass

KSS-Node styleguides

  • Organize your and maintain style components
  • Let your team and product owner know about the components
  • Prototype with SCSS and a little chunk of HTML before implementing in backend.

Documentation for any flavor of CSS that you’ll love to write. Human readable, machine parsable, and easy to remember.
