css - DIV位置问题

Question

我正在尝试将我的 DIV 定位如下

Logo /菜单/社交

前奏左/前奏右

背景图

中间 1

左下/右下

问题是目前 DIV 显示如下(参见 JSFiddle http://jsfiddle.net/A4Sn8/1/ ):

标志/菜单

社交

背景图

前奏左/前奏右

中间 1

左下

右下

总而言之，我的“社交”DIV 位于菜单下方而不是右侧。 Bottom-right DIV 在左下角下方而不是在其右侧，背景图片在 Intro-left 和 intro-right 之前而不是之后。

我该如何解决这个问题？

非常感谢

Answer 1

您将 CSS 规则与绝对像素大小和百分比混合在一起。这并不总是一个好主意。

你可能会遇到这个问题，因为你的 50px 的 padding-right 比剩余的 5% 的可用空间要大。

我不确定你想要达到什么目的，但我想底部元素应该在相同的高度上。试试这个:

#bottom-right {
    float: right;
    padding-right: 5%; /* you defined 50px instead! */
    width: 60%;
    background: #2ec4a6;
}
