What is Basic?

Basic was originally developed for client projects. Originally a stripped down version of the ZEN theme, basic has now become its own concept of a theme starter. Basic boasts a clean HTML structure with extensible CSS classes and ID's for unlimited theming possibilities as well as a top-down load order for improved SEO.

Basic's goal is to provide themers the building blocks needed to get their designs up and running quickly and simply.

What is SASS?

Sass is a meta-language on top of CSS that’s used to describe the style of a document cleanly and structurally, with more power than flat CSS allows. Sass both provides a simpler, more elegant syntax for CSS and implements various features that are useful for creating manageable stylesheets.

What will I Learn?

We will guide you through using Basic with SASS and Compass to kick-start your next Drupal theming project and show you how easy it is to get started. We will also cover the syntax and file structure of using SASS and how to get your development environment up

What we'll use Compass for... automajically compile our SASS files # Require any additional compass plugins here. project_type = :stand_alone # Set this to the root of your project when deployed: http_path = "/" css_dir = "css" sass_dir = "sass" images_dir = "images" javascripts_dir = "js" output_style = :compact # To enable relative paths to assets via compass helper functions. Uncomment: # relative_assets = true
  10. 10. But... as of SASS 3... files prefixed with underscore are ignored. sass --watch sass:css (sassdir:outputdir)
