: The use of hover, that is, the style setting made when the mouse pointer moves into the element
Example 1
<!DOCTYPE html><html lang="en"><head>
<meta charset="UTF-8">
<title>demo01</title>
<style>
*{
margin: 0;
padding: 0;
}
ul li{
width: 300px;
margin-top: 10px;
background: #ff0000;
}
ul li:hover{
background: #000000;
}
</style></head><body>
<ul>
<li></li>
<li></li>
<li></li>
</ul></body></html>
The above situation exists when the mouse pointer moves into an element and the element itself changes to a new style through:hover
Example 2
##
<!DOCTYPE html><html lang="en"><head>
<meta charset="UTF-8">
<title>demo01</title>
<style>
*{
margin: 0;
padding: 0;
}
.container{
width: 300px;
height: 300px;
border: 1px solid #ff9f5a;
}
.content{
width: 100px;
height: 100px;
background: #27e7ff;
}
.container:hover .content{
background: #000000;
}
</style></head><body>
<p class="container">
<p class="content"></p>
</p></body></html> In the above example , when there is a parent-child relationship, you can change the style of the child through the parent's :hover, written as .container:hover .content, there is a space after hover; but , Child: hover cannot change the style of the parent
Example 3<!DOCTYPE html><html lang="en"><head>
<meta charset="UTF-8">
<title>demo01</title>
<style>
*{
margin: 0;
padding: 0;
}
.container{
width: 300px;
height: 300px;
border: 1px solid #ff9f5a;
}
.content{
width: 100px;
height: 100px;
background: #27e7ff;
}
.container:hover +.content{
background: #000000;
}
</style></head><body>
<p class="container"></p>
<p class="content"></p></body></html>The above is the detailed content of Examples of usage of hover pseudo-class in CSS. For more information, please follow other related articles on the PHP Chinese website!
