Elastic is a simple CSS framework which eases creating elastic, fixed and liquid layouts with any column variations.
Using Elastic is like having a conversation with the code as it uses a declarative language.

It supports "combining classes" which helps creating almost any type of layout. And, it comes with a set of helper classes, to accomplish hard things by pure CSS like: same-height, full-width, and vertical-center.
Another nice feature is: both absolute & relative positioning can be used as no overlfow:hidden & clearfix are used.
