What is Bootstrap?

Bootstrap is a front-end framework for rapid development of web applications and websites. Bootstrap is based on HTML, CSS, and JAVASCRIPT.

Bootstrap is an open source product released on GitHub in August 2011. Bootstrap was developed by Mark Otto and Jacob Thornton of Twitter.

Bootstrap based on html5 and css3 has the following attractive features:

(1) Mobile devices first;

(2) Beautiful design;

(3) Friendly learning curve;

(4) Excellent compatibility;

(5) Responsive design;

(6) 12-column responsive grid structure;

(7) Style wizard document.

Customized JQuery plug-in, complete class library, based on Less, Sass, etc.

Bootstrap download

It can be downloaded from its Chinese official website. You can clearly see a big download button. In addition, it can also be downloaded through CDN, git command, npm, etc.

If you happened to read the sublime Text blog I wrote, you must know that we can install it directly through the plug-in. Just enter feth:manage at ctrl + shift + P and make the following settings:

"packages":
{
"Bootstrap": "https://github.com/twbs/bootstrap/releases/download/v3.3.6/bootstrap-3.3.6-dist.zip"
}

After that, you can download it directly through sublime Text. It is still the same step, but this time you enter fetch:package. Find Bootstrap. If the download is successful, you should see three folders in your folder: css, fonts and js, as follows:

You can see that every file in other folders except the font folder has two different versions, a full version of the file for easy viewing of the source code, such as: bootstrap.js and one for actual production situations. Compressed files such as bottstrap.min.js;

You can see many files in the font file, but its function is very simple. It is a file used to make icon icons, using the @font-face technology of CSS3.

In actual situations, if you want to use more icons, you can also find settings by yourself in Iconfont-Alibaba Vector Icon Library .

Global style

The core of the Bootstrap framework is a lightweight CSS basic code library. It does not blindly reset styles, but focuses on the basic performance of each browser to reduce development difficulty.

In order to enhance the consistency of cross-browser performance, Bootstrap uses Normalize.css. But instead of using this reset style blindly, some improvements were made on this basis to make it more in line with Bootstrap's design ideas.

Bootstrap retains and adheres to the basic styles of some browsers, solves some potential problems, improves the experience of some details, and sets basic global styles in layout and link styles. The specific instructions are as follows:

Remove body margin statement

Set the background color of the body to white

Sets basic font, font size and line height for typography

Set the global link color, and the underline style will be displayed only when the link is in the :hover state

This concludes the introduction to Bootstrap. In Bootstrap’s Chinese official website, there is a clear and detailed documentation. Let’s walk in with me

The world of Bootstrap!

What is 'this' in JavaScript?Mar 04, 2025 am 01:15 AM

Core points This in JavaScript usually refers to an object that "owns" the method, but it depends on how the function is called. When there is no current object, this refers to the global object. In a web browser, it is represented by window. When calling a function, this maintains the global object; but when calling an object constructor or any of its methods, this refers to an instance of the object. You can change the context of this using methods such as call(), apply(), and bind(). These methods call the function using the given this value and parameters. JavaScript is an excellent programming language. A few years ago, this sentence was
