html代码
<div class="parent">
<div class="child"></div>
</div>
css实现水平居中的各种方式
div.parent {
display: flex;
justify-content: center;
align-items: center;
}
div.parent {
position: relative;
}
div.child {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
div.child {
width: 50px;
height: 10px;
position: absolute;
top: 50%;
left: 50%;
margin-left: -25px;
margin-top: -5px;
}
div.child {
width: 50px;
height: 10px;
position: absolute;
left: 0;
top: 0;
right: 0;
bottom: 0;
margin: auto;
}
div.parent {
display: grid;
}
div.child {
justify-self: center;
align-self: center;
}
div.parent {
font-size: 0;
text-align: center;
&::before {
content: "";
display: inline-block;
width: 0;
height: 100%;
vertical-align: middle;
}
}
div.child{
display: inline-block;
vertical-align: middle;
}
div.parent{
display:flex;
}
div.child{
margin:auto;
}
div.parent {
display: table;
}
div.child {
display: table-cell
vertical-align: middle;
text-align: center;
}
- table-cell(父元素) + inline-block(子元素)
.parent {
display: table-cell;
height: 200px;
width: 200px;
background-color: orange;
text-align: center;
vertical-align: middle;
}
.child {
display: inline-block;
width: 100px;
height: 100px;
background-color: blue;
