垂直水平居中方案二:不知道宽高的情况下 absolute+transform
.parent { width:400px; height:400px; background: red; position: relative; } .child { position: absolute; left:50%; top:50%; transform: translate(-50%,-50%); }
垂直居中方案三:position+margin:auto
.parent { position:relative; width:200px; height:200px; background: red; } .child { width:80px; height:40px; background: yellow; position: absolute; left:0; top:0; right:0 ; bottom:0; margin:auto; }
垂直居中方案四:+ 多行文本的垂直居中 :table-cell+vertical-align:middle;

.parent { width:400px; height:200px; background:red; display: flex; justify-content:center; align-items:center; } .child { height:100px; width:100px; background:green; }
