Bootstrap is an open source toolkit for front-end development launched by Twitter. It is a CSS/HTML framework. It was developed by Twitter designers Mark Otto and Jacob Thornton. 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.

It is a framework for making web pages (currently the most popular WEB front-end framework), which means that you only need to write HTML tags to call its classes and you can quickly make a high-end web page. You don’t have to worry. Compatibility issues, many styles are provided for you to choose from!

For example, you need to make a website navigation, right? If you write it yourself, you need to write a lot of code, but if you use the bootstrap framework to write it, you only need to write the HTML tag and call the class name. !

Function:

Use the styles and components it provides to quickly write websites

To put it simply: it is an open source project to quickly build the front page of a website. (based on Jquery). You only need to understand the meanings of relevant classes, tag names, etc., and then when building the page, import bootstrap's JS, css, etc., and it will show the corresponding effects:
For example, HTML description: abbreviation ; The full content will be displayed when the mouse is hovered over abbreviations and abbreviations. Bootstrap implements enhanced styles for HTML elements. The abbreviation element has a title attribute and appears as a light dotted frame. When the mouse is moved over it, it will turn into a pointer with a "question mark". When you need a certain word or phrase in the paragraph text to have the above effect, you can just write it in that format. The additional class="initialism" makes the font size smaller, or it is not necessary. On the other hand: if you don't try bootstrap or other similar frameworks, then you have to write such effects yourself, which takes a long time to develop. Another example is Jquery's easyui, which is similar.
