Div Box中的Div框

Question

我已将页脚添加到EasyCareBath.com,我可以让div正常工作,除了".footer_box",它不会居中.我添加了"left:15%",当你把窗户向上吹时,它就不再对齐了.我错过了什么或者我对css做了太多的事吗？

.footer_spacer {
    height: 50px;   
}

改变你的.footer_box规则:

.footer_box {
    height: 236px;
    width: 1007px;
    margin: 0 auto;
    position: relative;
    }

margin: 0 auto;footer_box 的中心.

这position: relative;使得你的绝对定位列基于footer_box而不是身体定位.

旁注/类比我一直很喜欢:将'auto'想象为将橡皮筋连接到连接到页面边缘的项目的那一侧......在这种情况下,'auto'在右侧和左边,所以 - 如果从左右两侧拉出橡皮筋,它将始终居中,无论屏幕尺寸如何.
