Implementation method:
(Recommended tutorial: CSS tutorial)
1. Write an association using ul and li tags Structure (the parent-child relationship between ul and li is natural, and they are used in general association structures)
<ul class="nav">
<a href="#">服装</a>
<ul class="plat">
<li><a href="#">衬衫</a></li>
<li><a href="#">棉袄</a></li>
<li><a href="#">裤衩</a></li>
</ul>
</ul>2. Initialize the interface (a million-dollar beginning)
*{
padding: 0;
margin: 0;
}3. Give ul and a Add styles to tags (you can play freely here)
ul,a{
font-size: 20px;
list-style: none;
text-decoration: none;
background-color: #3C3C3C;
color: #FFFFFF;
width: 100px;
text-align: center;
border: 0px solid black;
border-radius: 5px; /*圆角*/
margin-top: 1px;
}
a{
display: block;
}4. Hide the content of the .plat part
.plat{
display: none;
}5. (Here comes the highlight) Use:hover for the first a tag Selector; implementation function: when the mouse moves over the a tag, the hidden part of the content is visible
.nav:hover .plat{
display: block;
clear: both;
}6. So far, the function has been implemented. You can add your own styles to optimize the user experience
For example:
Menu bar arranged horizontally:
.nav{
float: left;
margin-left: 1px;
}Mouse slide over the column to remind its position
`.plat li:hover>a{
background-color: dimgrey;
}`Effect:
