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. [1] 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.
Currently the most widely used versions are 2, 3 and 4. The latest version of 2 is 2.3.2, the latest version of 3 is 3.3.7, and the latest version of 4 is 4.3.0
