This time I will bring you the 2D conversion module in HTML and CSS. What are the precautions for the 2D conversion module in HTML and CSS. The following is a practical case, let's take a look.
1. 2D conversion module
2D conversion module
/*where deg is the unit, representing how many degrees*/
transform: rotate(45deg);/*
First parameter: Horizontal direction
Second parameter: Vertical direction
*/transform: translate(100px, 0px);/*
First parameter: Horizontal direction
Two parameters: vertical direction
Note:
If the value is 1, it means no change
If the value is greater than 1, it means it needs to be enlarged
If the value is less than 1, it means it needs to be reduced
If the horizontal and vertical scaling are the same, then it can be abbreviated as a parameter
*//*transform: scale(0.5, 0.5);*/transform: scale(1.5);/*
Note:
1. If multiple transformations are required, separate them with spaces.
2. The 2D transformation module will modify the coordinate system of the element, so the translation after rotation is not a horizontal translation.
*/transform: rotate(45deg ) translate(100px, 0px);
2D conversion module
/* 第一个参数:水平方向 第二个参数:垂直方向 注意点 取值有三种形式 具体像素 百分比 特殊关键字 */ /*transform-origin: 200px 0px;*/ /*transform-origin: 50% 50%;*/ /*transform-origin: 0% 0%;*/ /*transform-origin: center center;*/ transform-origin: left top;

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.

The roles of HTML, CSS and JavaScript in web development are: HTML is responsible for content structure, CSS is responsible for style, and JavaScript is responsible for dynamic behavior. 1. HTML defines the web page structure and content through tags to ensure semantics. 2. CSS controls the web page style through selectors and attributes to make it beautiful and easy to read. 3. JavaScript controls web page behavior through scripts to achieve dynamic and interactive functions.

HTML is the cornerstone of building web page structure. 1. HTML defines the content structure and semantics, and uses, etc. tags. 2. Provide semantic markers, such as, etc., to improve SEO effect. 3. To realize user interaction through tags, pay attention to form verification. 4. Use advanced elements such as, combined with JavaScript to achieve dynamic effects. 5. Common errors include unclosed labels and unquoted attribute values, and verification tools are required. 6. Optimization strategies include reducing HTTP requests, compressing HTML, using semantic tags, etc.

HTML is a language used to build web pages, defining web page structure and content through tags and attributes. 1) HTML organizes document structure through tags, such as,. 2) The browser parses HTML to build the DOM and renders the web page. 3) New features of HTML5, such as, enhance multimedia functions. 4) Common errors include unclosed labels and unquoted attribute values. 5) Optimization suggestions include using semantic tags and reducing file size.

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),
