如果您不需要垂直居中:
.container .stayInCenter {
position:relative; /* Not absolute */
margin:0 auto /* Make the left/right be centered */
}
如果您确实需要垂直居中:
.container .stayInCenter {
position:absolute;
/* Move to the center of the positioned parent */
left:50%; top:50%;
/* Give a fixed size */
width: 300px; height: 400px;
/* Move backwards by half the size, so the center is at 50% */
margin-left:-150px; margin-top:-200px;
}

你放一个固定的宽度,让我们说'宽度:500px'
并且你把'margin:auto'
如果你需要一个上边距,你可以写例如。 'margin:auto'之后的'margin-top:100px'
应该做的工作
