HTML Layout Guide: How to use pseudo-class selection for link style control

In web design, link style control is an integral part. By using HTML pseudo-class selectors, we can set styles for the status of links, so that users can more clearly identify the status of links when browsing web pages. This article explains how to use pseudo-class selectors to control link styles and provides some concrete code examples.

1. Overview

In HTML, links are usually created through the <a></a> tag. Common links include ordinary links, clicked links, mouse-over links, and links that have been visited. In order to control the style of these links, we can use pseudo-class selectors.

2. Examples of commonly used pseudo-class selectors

1. :link - Used to select all links that have not been clicked.

   a:link {
     color: blue;
     text-decoration: none;
   }

   In the above code, the :link selector selects all unclicked links, sets their color to blue and removes the underline.

2. :visited - Used to select all links that have been visited.

   a:visited {
     color: purple;
   }

   In the above code, the :visited selector selects all links that have been visited and sets their color to purple.

3. :hover - Used to select the state when the mouse is hovering over the link.

   a:hover {
     color: red;
     text-decoration: underline;
   }

   In the above code, the :hover selector selects the state of the mouse hovering over the link, sets its color to red and adds an underline.

4. :active - Used to select the state when the link is clicked.

   a:active {
     color: orange;
   }

   In the above code, the :active selector selects the state when the link is clicked and sets its color to orange.

3. Use pseudo-class selectors in combination

We can also use pseudo-class selectors in combination to achieve more precise link style control. For example, we can apply different styles depending on where the link is located.

/* 未被点击的链接 */
a:link {
  color: blue;
  text-decoration: none;
}

/* 已经被点击的链接 */
a:visited {
  color: purple;
}

/* 鼠标悬停在链接上的状态 */
a:hover {
  color: red;
  text-decoration: underline;
}

/* 点击链接时的状态 */
a:active {
  color: orange;
}

/* 在导航栏中的链接特殊样式 */
.navbar a:link,
.navbar a:visited {
  color: white;
  background: black;
  padding: 5px 10px;
  text-decoration: none;
}

.navbar a:hover {
  background: grey;
  color: black;
}

In the above code, we first define the general link style, and then set the style specifically for the link in the navigation bar.

4. Summary

By using HTML pseudo-class selectors, we can easily control the link style. This provides a better user experience and allows users to clearly identify the status of the link. In actual web design, we can flexibly combine and use pseudo-class selectors according to needs to achieve better results.
