flex布局，或者grid

.parent {
    display: flex/grid;
    justify-content: center;
    align-items: center;
}
.child {
   ...
}

绝对定位配合margin:auto

.parent {
    position: relative;
}
.child {
    position: absolute;
    top: 0;
    left: 0;
    bottom: 0;
    right: 0;
    margin: auto;
}

绝对定位配合transform实现

.parent {
    position: relative;
}
.child {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
}
