CSS frameworks are just CSS files. They provide pre-written CSS that you apply to your HTML using class names defined by the wireframe in its CSS file.
- Some structures focus on one specific task, for example. page layout. 960.gs is a good example of this.
- Some frameworks are more extensive and include pre-written CSS for typography, layout layout, print styles, etc. Blueprint is a good example of this.
Some frameworks also include reset styles, which tend to reset all styles for all HTML elements to very neutral defaults. They are automatically applied to all HTML elements, so you do not add classes to your HTML to apply them. Many of them are based on Eric Meyers CSS reset .
