样式链接

链接可以使用任何 CSS 属性(例如 colorfont-family背景等)。

例子

  a {
  color: hotpink;
}

自己尝试一下 →

<!DOCTYPE html>
<html>
<head>
<style>
a {
  color: hotpink;
}
</style>
</head>
<body>

<h2>Style a link with a color</h2>

<p><b><a href="default.asp" target="_blank">This is a link</a></b></p>

</body>
</html>


另外,链接可以设置样式 取决于他们所处的状态

四种链接状态是:

  • a:link - 正常的、未访问过的链接

  • a:visited - 用户访问过的链接

  • a:hover - 用户将鼠标悬停在其上时的链接

  • a:active - 单击后立即生成链接

例子

/* unvisited link */
a:link {
  color: red;
}
/* visited 
link */
a:visited {
  color: green;
}
/* mouse over link */
a:hover {
  color: hotpink;
}
/* selected link */
a:active {
   
color: blue;
}

自己尝试一下 →

<!DOCTYPE html>
<html>
<head>
<style>
/* unvisited link */
a:link {
  color: red;
}

/* visited link */
a:visited {
  color: green;
}

/* mouse over link */
a:hover {
  color: hotpink;
}

/* selected link */
a:active {
  color: blue;
}
</style>
</head>
<body>

<h2>Styling a link depending on state</h2>

<p><b><a href="default.asp" target="_blank">This is a link</a></b></p>
<p><b>Note:</b> a:hover MUST come after a:link and a:visited in the CSS definition in order to be effective.</p>
<p><b>Note:</b> a:active MUST come after a:hover in the CSS definition in order to be effective.</p>

</body>
</html>


在为几种链接状态设置样式时,有一些顺序规则:

  • a:hover 必须位于 a:link 和 a:visited 之后

  • a:active 必须在 a:hover 之后



文字装饰

text-decoration 属性主要用于删除链接中的下划线:

例子

a:link {
  text-decoration: none;
}

a:visited {
  text-decoration: none;
}

a:hover {
  text-decoration: underline;
}

a:active {
  text-decoration: underline;
}

自己尝试一下 →

<!DOCTYPE html>
<html>
<head>
<style>
a:link {
  text-decoration: none;
}

a:visited {
  text-decoration: none;
}

a:hover {
  text-decoration: underline;
}

a:active {
  text-decoration: underline;
}
</style>
</head>
<body>

<h2>Styling a link with text-decoration property</h2>

<p><b><a href="default.asp" target="_blank">This is a link</a></b></p>
<p><b>Note:</b> a:hover MUST come after a:link and a:visited in the CSS definition in order to be effective.</p>
<p><b>Note:</b> a:active MUST come after a:hover in the CSS definition in order to be effective.</p>

</body>
</html>



背景颜色

background-color 属性可用于指定链接的背景颜色:

例子

a:link {
  background-color: yellow;
}

a:visited {
  background-color: cyan;
}

a:hover {
  background-color: lightgreen;
}

a:active {
  background-color: hotpink;
} 

自己尝试一下 →

<!DOCTYPE html>
<html>
<head>
<style>
a:link {
  background-color: yellow;
}

a:visited {
  background-color: cyan;
}

a:hover {
  background-color: lightgreen;
}

a:active {
  background-color: hotpink;
} 
</style>
</head>
<body>

<h2>Styling a link with background-color property</h2>

<p><b><a href="default.asp" target="_blank">This is a link</a></b></p>
<p><b>Note:</b> a:hover MUST come after a:link and a:visited in the CSS definition in order to be effective.</p>
<p><b>Note:</b> a:active MUST come after a:hover in the CSS definition in order to be effective.</p>

</body>
</html>



链接按钮

此示例演示了一个更高级的示例,其中我们组合了多个 CSS 属性以将链接显示为框/按钮:

例子

a:link, a:visited {
  background-color: #f44336;
  
color: white;
  padding: 14px 25px;
  text-align: center; 
  text-decoration: none;
  display: inline-block;
}
a:hover, a:active {
  background-color: red;
}

自己尝试一下 →

<!DOCTYPE html>
<html>
<head>
<style>
a:link, a:visited {
  background-color: #f44336;
  color: white;
  padding: 14px 25px;
  text-align: center;
  text-decoration: none;
  display: inline-block;
}

a:hover, a:active {
  background-color: red;
}
</style>
</head>
<body>

<h2>Link Button</h2>

<p>A link styled as a button:</p>
<a href="default.asp" target="_blank">This is a link</a>

</body>
</html>
