css伪类中的:target的使用_html/css_WEB-ITnose
之前 :target伪类,我们已经接触过了. :target是css中伪类,主要是应用在url中的#链接,以及匹配对应的id名称.例如下面的例子:
代码名称
http://www.wutongwei.com/#home
对应的home 的结构为
代码名称
this is target
这种状态,我们可以通过CSS来体现他的效果.
代码名称
:target{
color:#ff6600;
}
这时候,当浏览这个链接的时候,就会将对应的有id的元素设置他的文字颜色为 #ff6600;
一个页面当然可以有多个target的目标,这时候,这个伪类的样式就适用所有的target元素,如果我们只是改变某个target的话.
这时候我们最好是在CSS上做好选择器的处理.比如
代码名称
this is target
this is another target
CSS上则使用:
代码名称
#home:target{
color:#ff6600;
}
这时候,当浏览http://www.wutongwei.com/#second的时候就不会应用伪类的CSS样式了.
target伪类使用经验:
1. 在在页面上做跳转时,要显示某种状态.
2. 有必要使用这个状态的元素.
3. 接受浏览器的history.
像target这种行为,我们可以在页面上的章节跳转或者评论第跳转等目标跳转.
或者使用在我们常说的tabs上使用.之前我们通常是使用JS来完成tabs的操作.现在可以通过这个伪类来实现.还有就是菜单都可以用这个来实现,等等.

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 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 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, CSS and JavaScript are the core technologies for building modern web pages: 1. HTML defines the web page structure, 2. CSS is responsible for the appearance of the web page, 3. JavaScript provides web page dynamics and interactivity, and they work together to create a website with a good user experience.
