Question

我正在使用bootstrap并使用带有2个全宽div的容器流体，我试图找出为什么我可以看到一个盒子阴影，而不是另一个。这就是我所拥有的，我希望有人可以解释。现在发生的事情是第一个div没有盒子阴影，第二个div显示没有问题。

.header-logo-bg {

.header-bg { background: url('../img/diagonal-overlay.png') repeat #ebe0b1; padding: 30px; box-shadow: 0 8px 4px #aaa;}

Answer 1

底部<div>具有不透明的背景和更高的z-index，因此只是悬停在另一个阴影上并遮挡它。尝试在顶部div上使用下边距添加一些空格。

2个Div和2个Box Shadows
