bootstrap is a framework for making web pages (currently the most popular WEB front-end framework ), that is to say, you only need to write HTML tags and call its classes, and you can quickly create a high-end web page. You don’t have to worry about compatibility issues, and 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
You only need to reference some defined classes, that is, class names , you can create a web page that already has a very beautiful style, and it supports self-adaptation. It is a very good framework.
To put it simply: it is an open source project (based on Jquery) to quickly build the front-end page of a website. You only need to understand the meaning of the 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; when the mouse is hovered over abbreviations and abbreviations, the complete content will be displayed. Bootstrap implements enhanced styles for HTML elements.
The abbreviation element has the title attribute, and its appearance 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" will make the font size smaller. You don’t have to.
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.
