![css中有哪些方法可以实现垂直居中](https://img.php.cn/upload/article/000/000/041/5e781d403926e434.jpg)
css实现垂直居中的方法如下:
1、利用line-height实现居中,这种方法适合纯文字类的;
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | <!-- css -->
<style>
.parents {
height: 400px;
line-height: 400px;
width: 400px;
border: 1px solid red;
text-align: center;
}
.child {
background-color: blue;
color: #fff;
}
</style>
</head>
<body>
<!-- html -->
<div class = "parents" >
<span class = "child" >css布局,实现垂直居中</span>
</div>
</body>

2、通过设置父容器相对定位,子级设置绝对定位,标签通过margin实现自适应居中;
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | <!-- css -->
<style>
.parents {
height: 400px;
width: 400px;
border: 1px solid red;
position: relative;
}
.child {
width: 200px;
height: 100px;
line-height: 100px;
text-align: center;
color: #fff;
background-color: blue;
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
margin: auto;
}
</style>
</head>
<body>
<!-- html -->
<div class = "parents" >
<span class = "child" >css布局,实现垂直居中</span>
</div>

3、弹性布局flex 父级设置display: flex; 子级设置margin为auto实现自适应居中;
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | <!-- css -->
<style>
.parents {
height: 400px;
width: 400px;
border: 1px solid red;
display: flex;
}
.child {
width: 200px;
height: 100px;
line-height: 100px;
text-align: center;
color: #333;
background-color: yellow;
margin: auto;
}
</style>
</head>
<body>
<!-- html -->
<div class = "parents" >
<span class = "child" >css布局,实现垂直居中</span>

4、父级设置相对定位,子级设置绝对定位,并且通过位移transform实现;
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | <!-- css -->
<style>
.parents {
height: 400px;
width: 400px;
border: 1px solid red;
position: relative;
}
.child {
width: 200px;
height: 100px;
line-height: 100px;
text-align: center;
color: #fff;
background-color: green;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
</style>
</head>
<body>
<!-- html -->
<div class = "parents" >
<span class = "child" >css布局,实现垂直居中</span>
</div>

5、父级设置弹性盒子,并设置弹性盒子相关属性;
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | <!-- css -->
<style>
.parents {
height: 400px;
width: 400px;
border: 1px solid red;
display: flex;
justify-content: center;
align-items: center;
}
.child {
width: 200px;
height: 100px;
color: black;
background-color: orange;
}
</style>
</head>
<body>
<!-- html -->
<div class = "parents" >
<span class = "child" ></span>
</div>
</body>

6、网格布局,父级通过转换成表格形式,然后子级设置行内或行内块实现。(需要注意的是:vertical-align: middle使用的前提条件是内联元素以及display值为table-cell的元素)。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | <!-- css -->
<style>
.parents {
height: 400px;
width: 400px;
border: 1px solid red;
display: table-cell;
text-align: center;
vertical-align: middle;
}
.child {
width: 200px;
height: 100px;
color: #fff;
background-color: blue;
display: inline-block;
}
</style>
</head>
<body>
<!-- html -->
<div class = "parents" >
<span class = "child" ></span>
