将div固定在另一个div上方的底部

时间：2013-01-11 19:10:47

标签： html css

我一直在开发一个带水平滚动的移动布局。

但现在我遇到了一个问题：

有一个NAV元素粘在页面的底部，没有问题，但我希望在顶部和底部实现带有“框架”的“软木板”效果。再一次，最重要的一个根本没有问题，但是我在试图让底部停留在底部并且高于NAV栏时遇到了很多麻烦。

这是这样的： enter image description here

基本上，红色方块是当前视图/屏幕，导航栏固定在底部，如果我滚动到另一个部分，它会按预期保持在屏幕底部，顶部蓝色条（顶部框架）也是如此）。

如何让底部的蓝色条保持在预期/示例位置？

我尝试了从边距，填充，高度和最小高度的一切，但无法达到预期的效果。 任何人都可以指出我做错了吗？

如果我正确阅读，问题是背景是悬挂在元素的顶部而不是底部？

将background-position: bottom;添加到该元素的样式中。

<小时/> 编辑以添加我的解决方案css：

  • HTML与原始帖子相同
  • “Meyerweb”CSS保持不变
  • 更改了CSS：
html, body { 
    height: 100%;
    overflow: hidden;

body {
    overflow-x: auto;
    /* allows that horizontal scrolling */
}

#wrapper {

    top: 0px;
    bottom: 0px;
    /* ^-- these three lines replace height:100%
     * and correct some layout quirks */
}
#wrapper > section { 
    display: inline-block; 
    height: 100%;
    margin-left: -4px;
    margin-bottom: -4px;
}

#wrapper > section:first-child  {
    margin-left: 0px;
    /* combined with -4px margin above, eliminates gaps between sections */
}

#wrapper > section, section > header, section > div {

    /* not sure why 25%, since you seem to only
     * have three sections... but either way,

使用“bottom：0px”代替保证金。我没有深入研究这个，但我有一个自己的项目，div与底部对齐，并且已修复。

我保留了桌子，整齐地对齐了一切（即使是那些尴尬的空间＆＃34;）然后保持一切整洁的秘密就是使用溢出：隐藏在体内。 现在，这确实存在其他问题，例如你现在无法垂直或水平滚动，但鉴于这不是问题（导航应该使用导航栏来模拟不同的视图），它现在可以正常工作，没有任何问题JS。
