The meaning and meaning of semantic HTML:
1. What is semantic HTML?
Semantic HTML means the right tags do the right thing, making it easier for developers to read and write more elegant code while allowing web crawlers to parse it well.
2. Why should we achieve semantics?
1. It is beneficial to SEO and helps search engine crawlers to better understand our web pages, thereby obtaining more effective information and increasing the weight of the web pages.
2. When there is no CSS, the structure of the web page can be clearly seen and the readability is enhanced.
3. It facilitates team development and maintenance. Semantic HTML can make it easier for developers to understand, thereby improving the team's efficiency and coordination capabilities.
4. Support browser rendering for multiple terminal devices.
3. How to do semantic HTML?
When doing front-end development, remember: HTML tells us what a piece of content is (or its meaning), not what it looks like. Its appearance should be determined by CSS. (Separation of structure and style!)
Writing semantic HTML structure is actually very simple. First, master the semantics of each tag in HTML. When you see the content, think about what tags can be used to better describe it. Use whatever label you want.

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

The future of HTML is full of infinite possibilities. 1) New features and standards will include more semantic tags and the popularity of WebComponents. 2) The web design trend will continue to develop towards responsive and accessible design. 3) Performance optimization will improve the user experience through responsive image loading and lazy loading technologies.

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),
