水平居中方案方案一：text-align inline-block
<div id="parent1">
<div class="child">水平居中</div>
</div>
#parent1{
text-align: center;
background:#ddd;
margin-bottom:20px;
}
#parent1 .child{
display: inline-block;
background:#666;
color:#fff;
}
<div id="parent2">
<div class="child">水平居中</div>
</div>
#parent2{
text-align: center;
background:#ddd;
margin-bottom:20px;
}
#parent2 .child{
display: table;
margin: 0 auto;
background:#666;
color:#fff;
}
<div id="parent3">
<div class="child">水平居中</div>
</div>
#parent3{
position: relative;
background:#ddd;
margin-bottom:20px;
}
#parent3 .child{
position: absolute;
left: 50%;
transform: translateX(-50%);
background:#666;
color:#fff;
}
<div id="parent4">
<div class="child">水平居中</div>
</div>
#parent4{
display: flex;
justify-content: center;
background:#ddd;
margin-bottom:20px;
}
#parent4 .child{
margin:0 auto;
background:#666;
color:#fff;
}
- 这种方法适用于单行文本垂直居中,如果文本内容太长，出现了换行，换行后的内容会溢出
<div id="example1">
单行文字垂直居中
</div>
#example1 {
height: 100px;
line-height: 100px;
background: #161616;
color: #fff;
width: 200px;
}
<div id="example2">
<div class="inner">块区域垂直居中</div>
</div>
#example2 {
height: 100px;
background: #161616;
color: #fff;
width: 400px;
overflow: hidden;
display: table;
margin-bottom:20px;
}
#example2 .inner{
display: table-cell;
vertical-align: middle;
height: 50px;
background:#999;
}
<div id="example3">
<div class="inner">块区域垂直居中</div>
</div>
#example3 {
height: 100px;
background: #161616;
color: #fff;
width: 400px;
overflow: hidden;
margin-bottom:20px;
}
#example3 .inner{
margin-left: auto;
margin-right: auto;
margin-top: calc((100px - 50px)/2);
height: 50px;
background:#999;
}
<div id="example4">
<div class="inner">块区域垂直居中</div>
</div>
#example4 {
width: 400px;
height: 100px;
background: #161616;
color: #fff;
position: relative;
margin-bottom:20px;
}
#example4 .inner{

margin-top: -25px;
margin-left: -100px;

<div id="example5">
<div class="inner">块区域垂直居中</div>
</div>
#example5 {
