It's named Gridless, because the CSS does not come with pre-made grid layouts.
It leaves this to the developer and the requirements of his project.
The framework just adds all the needed rules for styling any HTML 4 and HTML 5 elements that would ever be encountered in a page's code.
A demo is included with the download package.
Here are some key features of "Gridless":
· Responsive (responds to the user's device screen width with the adequated CSS)
· Progressive enhancement and mobile first
· Cross-browser compatible (even IE6 and 7)
· CSS normalization instead of CSS reset
· Beautiful typography with a vertical rhythm and heading sizes based on golden ratio
· Print styles optimized for performance
· Optimal caching
· HTML5 and CSS3 ready
· Safe CSS hacks instead of conditional class names/stylesheets
· Micro clearfix hack
· A well-organized folder structure
