Bootstrap, from Twitter, is currently the most popular front-end framework. Bootstrap is based on HTML, CSS, and JAVASCRIPT. It is simple and flexible, making web development faster. Let me first tell you the key points of learning.
Learning points:
1. Giant screen component
2. Header component
3. Thumbnail component
4. Alert box component
In this lesson we will mainly study the four component functions of Bootstrap: giant screen component, page header component, thumbnail component and warning box component.
1. Giant screen component
The giant screen component is mainly used to display key areas of the website.
//在固定的范围内,有圆角 <div class="container"> <div class="jumbotron"> <h2 id="网站标题">网站标题</h2> <p> 这是一个学习性的网站! </p> <p> <a href="#" class="btn btn-default">更多内容</a> </p> </div> </div> //100%全屏,没有圆角 <div class="jumbotron"> <div class="container"> <h2 id="网站标题">网站标题</h2> <p> 这是一个学习性的网站! </p> <p> <a href="#" class="btn btn-default">更多内容</a> </p> </div> </div>
2. Header component
//增加一些空间 <div class="page-header"> <h1 id="大标题-small-小标题-small">大标题 <small>小标题</small></h1> </div>

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

JavaScript can be used for front-end and back-end development. The front-end enhances the user experience through DOM operations, and the back-end handles server tasks through Node.js. 1. Front-end example: Change the content of the web page text. 2. Backend example: Create a Node.js server.

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.

The power of the JavaScript framework lies in simplifying development, improving user experience and application performance. When choosing a framework, consider: 1. Project size and complexity, 2. Team experience, 3. Ecosystem and community support.

Introduction I know you may find it strange, what exactly does JavaScript, C and browser have to do? They seem to be unrelated, but in fact, they play a very important role in modern web development. Today we will discuss the close connection between these three. Through this article, you will learn how JavaScript runs in the browser, the role of C in the browser engine, and how they work together to drive rendering and interaction of web pages. We all know the relationship between JavaScript and browser. JavaScript is the core language of front-end development. It runs directly in the browser, making web pages vivid and interesting. Have you ever wondered why JavaScr

Node.js excels at efficient I/O, largely thanks to streams. Streams process data incrementally, avoiding memory overload—ideal for large files, network tasks, and real-time applications. Combining streams with TypeScript's type safety creates a powe

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
