html单行文本垂直居中
单行文本垂直居中,在于使用line-height
若是line-height = height 可以实现垂直居中
若是line-height < height 文字偏上
若是line-height > height 文本篇下
实验案例:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>导航栏-行内块元素</title>
<style>
.a1{
display: inline-block;
width: 200px;
height: 40px;
background-color: #C0C0C0;
text-align: center;
text-decoration: none;
line-height: 40px;
}
.a2{
display: inline-block;
width: 200px;
height: 40px;
background-color: #C0C0C0;
text-align: center;
text-decoration: none;
line-height: 50px;
}
.a3{
display: inline-block;
width: 200px;
height: 40px;
background-color: #C0C0C0;
text-align: center;
text-decoration: none;
line-height: 30px;
}
</style>
</head>
<body>
<a href="#" class="a1">文本居中</a>
<br /><br />
<a href="#" class="a2">文本偏下</a>
<br /><br />
<a href="#" class="a3">文本偏上</a>
</body>
</html>
