CSS (Cascading Style Sheet) is a language used for web design. It includes many functions, including beautifying the page by changing the attributes of text. This article will introduce some common CSS text properties and how to implement them in web pages.
1. Font attributes
Font attributes can be used to control the font, size, color, style and spacing of text. Specific attributes include:
- font-family: used to set the name of the font or a list of font family names. Multiple ones are separated by commas. The browser will search for the font in order of the list.
- font-size: Used to set the size of the font, which can be specified in pixels (px), percentage (%), EM, rem and other units.
- font-weight: Used to set the thickness of the font, which can be specified using numbers, keywords bold and bolder, etc.
- font-style: Used to set whether the font is bold or italic. You can use the keywords italic and oblique to specify.
- line-height: used to set the line spacing, you can use units such as pixels or percentages.
- text-align: used to set the horizontal alignment of text, including left, center, right, justify, etc.
2. Text attributes
Text attributes can be used to control text decoration, indentation, line wrapping, etc. Specific attributes include:
- text-decoration: used to set the underline, strikethrough, and text decoration lines of text. Can be specified using the keywords underline, overline, line-through and none.
- text-indent: used to set the indent of text, you can use units such as pixels or percentages.
- text-transform: used to set the case conversion method of text, including uppercase, lowercase and capitalize, etc.
- white-space: used to set the text processing method, including normal, nowrap, pre-wrap, etc.
3. Color attribute
The color attribute is used to control the color of text and background. Colors can be specified using CSS color names or hexadecimal values. Among them:
- color attribute is used to set the color of text.
- The background-color property is used to set the color of the background.
4. Selector
In addition to font, text and color attributes, selectors are also important elements in CSS. Selectors are used to specify the HTML elements that need to be modified. For example:
- Tag selector: used to select specific types of HTML elements. For example, p will change all paragraph elements.
- Class selector: used to select HTML elements with the same class name. For example, .h1 will change all elements using the h1 class.
- ID selector: used to select HTML elements with the same identifier. For example, #header will select the element on the page with the id "header".
- Wildcard selector: used to select all HTML elements. For example, * will select all elements in the web page.
5. Example walkthrough
Here, we will demonstrate how to use CSS to change text attributes and color attributes. We will create a simple web page and change the text and color properties of some of its elements.
- First, add the following code in the HTML document:
<title>CSS改变文字</title> <link rel="stylesheet" type="text/css" href="styles.css">
<h1 id="这是标题">这是标题</h1> <p class="text">这是一段正文,包含有一些链接:<a href="#">链接1</a>和<a href="#">链接2</a></p> <ul class="list"> <li>列表项1</li> <li>列表项2</li> <li>列表项3</li> </ul>
- In the same folder Create a style sheet file styles.css and add the following styles:
.title {
font-family: Arial, sans-serif; font-size: 36px; font-weight: bold; text-align: center; color: navy;
}
.text {
font-family: "Times New Roman", Times, serif; font-size: 18px; line-height: 1.5em; text-indent: 25px; color: #333;
}
.list {
font-family: Verdana, sans-serif; font-size: 16px; text-transform: uppercase; color: maroon;
}
- Open the browser and preview the HTML file. You can see that the text and color attributes have been modified.
Modifying text and color attributes through CSS can make the page look more beautiful and personalized. Whether it's font styles, text formatting, or color properties, CSS offers a variety of choices and flexibility. When you start writing your web pages, try using different selectors and attributes to make your site stand out.

React is a front-end framework for building user interfaces; a back-end framework is used to build server-side applications. React provides componentized and efficient UI updates, and the backend framework provides a complete backend service solution. When choosing a technology stack, project requirements, team skills, and scalability should be considered.

The relationship between HTML and React is the core of front-end development, and they jointly build the user interface of modern web applications. 1) HTML defines the content structure and semantics, and React builds a dynamic interface through componentization. 2) React components use JSX syntax to embed HTML to achieve intelligent rendering. 3) Component life cycle manages HTML rendering and updates dynamically according to state and attributes. 4) Use components to optimize HTML structure and improve maintainability. 5) Performance optimization includes avoiding unnecessary rendering, using key attributes, and keeping the component single responsibility.

React is the preferred tool for building interactive front-end experiences. 1) React simplifies UI development through componentization and virtual DOM. 2) Components are divided into function components and class components. Function components are simpler and class components provide more life cycle methods. 3) The working principle of React relies on virtual DOM and reconciliation algorithm to improve performance. 4) State management uses useState or this.state, and life cycle methods such as componentDidMount are used for specific logic. 5) Basic usage includes creating components and managing state, and advanced usage involves custom hooks and performance optimization. 6) Common errors include improper status updates and performance issues, debugging skills include using ReactDevTools and Excellent

React is a JavaScript library for building user interfaces, with its core components and state management. 1) Simplify UI development through componentization and state management. 2) The working principle includes reconciliation and rendering, and optimization can be implemented through React.memo and useMemo. 3) The basic usage is to create and render components, and the advanced usage includes using Hooks and ContextAPI. 4) Common errors such as improper status update, you can use ReactDevTools to debug. 5) Performance optimization includes using React.memo, virtualization lists and CodeSplitting, and keeping code readable and maintainable is best practice.

React combines JSX and HTML to improve user experience. 1) JSX embeds HTML to make development more intuitive. 2) The virtual DOM mechanism optimizes performance and reduces DOM operations. 3) Component-based management UI to improve maintainability. 4) State management and event processing enhance interactivity.

React components can be defined by functions or classes, encapsulating UI logic and accepting input data through props. 1) Define components: Use functions or classes to return React elements. 2) Rendering component: React calls render method or executes function component. 3) Multiplexing components: pass data through props to build a complex UI. The lifecycle approach of components allows logic to be executed at different stages, improving development efficiency and code maintainability.

React Strict Mode is a development tool that highlights potential issues in React applications by activating additional checks and warnings. It helps identify legacy code, unsafe lifecycles, and side effects, encouraging modern React practices.

React Fragments allow grouping children without extra DOM nodes, enhancing structure, performance, and accessibility. They support keys for efficient list rendering.

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),
