This article mainly introduces what are the core components of bootstrap, which are introduced in great detail and have certain reference value. Friends who are interested must finish reading them.

Bootstrap makes front-end development faster and easier. All developers can get started quickly, all devices can be adapted, and all projects are applicable.

Although you can use the CSS stylesheet provided by Bootstrap directly, don't forget that the source code for Bootstrap is based on the most popular CSS preprocessing scripts-Less and Sass. You can develop quickly with precompiled CSS files, or you can customize the styles you need from the source code. (recommended study: Bootstrap video tutorial)

With the help of Bootstrap, your website and applications can quickly and effectively adapt to phones, tablets, and PC devices through the same code, all thanks to CSS Media query (Media Query).

Bootstrap provides comprehensive and beautiful documentation. You can find all the detailed documentation on HTML elements, HTML and CSS components, and jQuery plug-ins here.

Three core components of Bootstrap

Basic CSS: set global CSS style, basic HTML elements can be styled and enhanced through class; and advanced grid system

Components: numerous reusable components, including font icons, drop-down menus, navigation, warning bars, pop-ups, and more

JS plug-ins: Bootstrap comes with 13 jQuery plug-ins that give "life" to components in Bootstrap.

Mobile device priority

Mobile device priority is the most significant change in Bootstrap 3.

In previous versions of Bootstrap (until 2.x), you needed to reference another CSS manually to make the entire project friendly to mobile devices.

It's different now. Bootstrap 3's default CSS is inherently mobile-friendly.

Bootstrap 3 is designed to give priority to mobile devices, followed by desktop devices. This is actually a very timely change, as more and more users are using mobile devices.

In order to make the website developed by Bootstrap friendly to mobile devices and ensure proper drawing and touchscreen scaling, you need to add viewport meta tags to the head of the web page.

As follows:

The width property controls the width of the device. Assuming that your site will be viewed by devices with different screen resolutions, setting it to device-width ensures that it is correctly rendered on different devices.

Initial-scale=1.0 ensures that when the web page loads, it is rendered at 1:1 without any scaling.

On mobile device browsers, you can disable its zooming function by adding user-scalable=no to the viewport meta tag
