Helium is a lightweight front end framework similar to popular front end frameworks Twitter bootstrap and Foundation built with HTML5 and CSS3. It uses popular CSS preprocessor SASS and maxin library compass. The aim of helium is to make it lighter and thinner than twitter bootstrap and foundation as compiled css only weighs 30k as compared to bootstrap 100K and foundation 200k.
Helium uses 960 grid system. The grid system of helium is based on fluid-width columns as found in Zurb Foundation. Each column’s width is defined as a percentage rather than a fixed number of pixels. It also support nesting of grids.
As the basic aim of helium is to make it much lighter and faster, so it comes packed with default styling of some basic markup tags such as buttons, forms and labels etc.
