Developed and maintained by web designer Joni Korpi, Less Framework is a new generation CSS framework that is built perfectly for any web browser such as Chrome, Safari 3.0+, Firefox 3.0+ and Internet Explorer 7+, and any device including the Apple iPhone and iPad. It’s a lightweight CSS framework for building flexible multi-column website layouts. LESS contains an eight-column grid optimized for a line-height of 24px, and a set of typography presets based on the golden ratio that fit into the grid’s vertical rhythm. Webpage can collapse automatically into a single column in old browsers and on small width screens. LESS CSS framework requires a single.css, multi.css, HTML5.js and switcher.js to function.
