Framework
Pure by Yahoo! is a lightweight modular framework in pure CSS with options of combining
components as needed. Cascading Style Sheets (CSS) technology is widely used for bringing
uniformity to the look and feel of the various pages and user interfaces of markup languages
like HTML or XML. Pure.CSS generates a set of small responsive modules to be used with web
projects. It is best suited for smaller projects which do not require to indulge in the hassles of a
full-featured framework but can get away with using only a few specific components which are
available in built. CSS can further be customized to make it project specific and be used on top
of the minimal Pure. In this way Pure avoids the problem of unused CSS, making it very light.
It is a very popular framework supported by most commonly used browsers like the latest
versions of Firefox, Chrome, Safari; IE7+; iOS 6.x, 7.x; Android 4.x and licensed under Yahoo!
