Twitter has launched Bootstrap-a front-end toolkit for rapidly developing web applications. Twitter says Bootstrap “uses some of the latest browser techniques to provide you with stylish typography, forms, buttons, tables, grids, navigation and everything else you need in a super tiny (only 6k with gzip) resource.” It is a collection of CSS and HTML conventions.
Bootstrap is the 46th code repository Twitter staff has created on Github.These new tools don’t have to be used in developing anything related to Twitter exclusively.
Bootstrap is just CSS, but it’s built with Less, a flexible pre-processor that offers much more power and flexibility than regular CSS. With Less, you gain a range of features like nested declarations, variables, mixins, operations, and color functions.
