SVG 元素用于将一串文本放置到一条指定的路径上。例如可以将文本串放置到一个圆上,做出非常酷的效果。对于不同的浏览器,路径文字的效果也略有不同。下面是一个简单的路径文字的例子:
<svg xmlns="http://www.w3.org/2000/svg"> <defs> <path id="myTextPath" d="M75,20 a1,1 0 0,0 100,0 " /> </defs> <text x="10" y="100" style="stroke: #000000;"> <textPath xlink:href="#myTextPath" > Text along a curved path... </textPath> </text> </svg>
下面是上面代码的返回结果:
元素中的路径有一个ID属性。这个ID属性被元素的xlink:href属性引用,作为文字的路径。
注意如果路径的长度小于文本的长度,那么只有在路径内的文字会被绘制。
你也可以使用更复杂的路径,下面是一个比较复杂的路径制作路径文字的例子:
<defs> <path id="myTextPath2" d="M75,20 l100,0 l100,30 q0,100 150,100"/> </defs> <text x="10" y="100" style="stroke: #000000;"> <textPath xlink:href="#myTextPath2"> Text along a more advanced path with lines and curves. </textPath> </text>
这个例子中。路径包括一条直线,一条斜线和一条曲线,得到的结果如下所示:
我们还可以制作路径文字动画,这要使用到元素,这个内容将在后面的文章中介绍,这里先来看一下它的效果:

H5 improves web user experience with multimedia support, offline storage and performance optimization. 1) Multimedia support: H5 and elements simplify development and improve user experience. 2) Offline storage: WebStorage and IndexedDB allow offline use to improve the experience. 3) Performance optimization: WebWorkers and elements optimize performance to reduce bandwidth consumption.

HTML5 code consists of tags, elements and attributes: 1. The tag defines the content type and is surrounded by angle brackets, such as. 2. Elements are composed of start tags, contents and end tags, such as contents. 3. Attributes define key-value pairs in the start tag, enhance functions, such as.

Support multimedia elements and embed media without plug-ins. 3. Forms enhance new input types and verification properties, simplifying the verification process. 4. Offer offline and local storage functions to improve web page performance and user experience.

Best practices for H5 code include: 1. Use correct DOCTYPE declarations and character encoding; 2. Use semantic tags; 3. Reduce HTTP requests; 4. Use asynchronous loading; 5. Optimize images. These practices can improve the efficiency, maintainability and user experience of web pages.

Web standards and technologies have evolved from HTML4, CSS2 and simple JavaScript to date and have undergone significant developments. 1) HTML5 introduces APIs such as Canvas and WebStorage, which enhances the complexity and interactivity of web applications. 2) CSS3 adds animation and transition functions to make the page more effective. 3) JavaScript improves development efficiency and code readability through modern syntax of Node.js and ES6, such as arrow functions and classes. These changes have promoted the development of performance optimization and best practices of web applications.

H5 is not just the abbreviation of HTML5, it represents a wider modern web development technology ecosystem: 1. H5 includes HTML5, CSS3, JavaScript and related APIs and technologies; 2. It provides a richer, interactive and smooth user experience, and can run seamlessly on multiple devices; 3. Using the H5 technology stack, you can create responsive web pages and complex interactive functions.

H5 and HTML5 refer to the same thing, namely HTML5. HTML5 is the fifth version of HTML, bringing new features such as semantic tags, multimedia support, canvas and graphics, offline storage and local storage, improving the expressiveness and interactivity of web pages.
