Bootstrap is a simple, intuitive, and powerful front-end development framework based on HTML, CSS, and JavaScript developed by Mark Otto and Jacob Thornton, designers of the American Twitter company, to make Web development faster. Bootstrap provides elegant HTML and CSS specifications, which are written in the dynamic CSS language Less. Bootstrap has been very popular since its launch and has been a popular open source project on GitHub, including NASA's MSNBC (Microsoft National Broadcasting Company) Breaking News. Some frameworks that are familiar to domestic mobile developers, such as the WeX5 front-end open source framework, are also performance optimized based on the Bootstrap source code.

Bootstrap is the fourth most "Starred" project on GitHub. Starred more than 133,000 times and branched more than 65,000 times.
