+ 负margin
.father { position: relative; } .son { position: absolute; left: 50%; top: 50%; margin-left: -50px; margin-top: -50px; }
3. absolute
+ transform
.father { position: relative; } .son { position: absolute; left: 50%; top: 50%; transform: translate(-50%, -50%); }
4. absolute
+ margin: auto
.father { position: relative; } .son { position: absolute; left: 0; right: 0; top: 0; bottom: 0; margin: auto; }
