Bootstrap – Front-end Framework

Bootstrap is a free and open source mobile-first HTML, CSS, JavaScript front-end framework. It is designed to make web development faster and easier. It was developed by Twitter’s Mark Otto and Jacob Thornton with the first release in 2011. It is now released under the MIT License.


Designed for everyone, everywhere – Bootstrap makes front-end web development faster and easier. It’s made for folks of all skill levels, devices of all shapes, and projects of all sizes.

Build responsive, mobile-first projects on the web with the world’s most popular front-end component library.

Bootstrap is an open source toolkit for developing with HTML, CSS, and JS. Quickly prototype your ideas or build your entire app with our Sass variables and mixins, responsive grid system, extensive prebuilt components, and powerful plugins built on jQuery.



  • Preprocessors – Bootstrap ships with vanilla CSS, but its source code utilizes the two most popular CSS preprocessors, Less and Sass. Quickly get started with precompiled CSS or build on the source.
  • One framework, every device – Bootstrap easily and efficiently scales your websites and applications with a single code base, from phones to tablets to desktops with CSS media queries.
