Compass Core provides a common set of tools for use across all frameworks.

Compass Core Modules

• Compass Core: Reset Module – invokes a comprehensive reset mixin (+global-reset) to make all browsers have the same starting style. A number of targeted mixin resets are also defined: nested context, HTML5, box-model, typography, list-style, focus, etc.
• Compass Core: Utilities Module – Helpers/mixins that provide common styling patterns. e.g., clearfix (two varieties), cross-browser floats, cross-browser min-width and min-height, IE6 hacks, tag cloud, link colors (LVFHA), bullets or no bullets, horizontal and inline lists, alternating colors for tables, image replacement, etc.
• Compass Core: Layout Module – Helpers/mixins for common layout patterns that aren’t specifically provided by one of the framework modules. Currently only a “sticky-footer” mixin is provided to help pin a footer to the bottom of the screen when page content is too short.
