Bootstrap streamlined tutorial_javascript skills-JS Tutorial-php.cn

Bootstrap, from Twitter, is a very popular front-end framework. Bootstrap is based on HTML, CSS, and JAVASCRIPT. It is simple and flexible, making web development faster. [1] It was developed by Twitter designers Mark Otto and Jacob Thornton and is a CSS/HTML framework. 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. [2] 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.

Features:

Bootstrap is developed based on HTML5 and CSS3. It is more personalized and user-friendly based on jQuery, forming its own unique website style and is compatible with most jQuery plug-ins.

Bootstrap is very easy to learn, and the styles it provides are very beautiful. With a little bit of learning, you can create beautiful pages.
