Javascript 内容和页脚重叠，不将页脚推到底部

有人能告诉我为什么我的content和foter是重叠的，为什么内容不会把页脚推到底

除了这两个问题外，背景覆盖和背景渐变似乎实际上并没有设置为100%，因为如果内容扩展到很远的地方，它们就不会让黑色背景暴露出来

我这里有它的实况版本：

或者简单地尝试
overlay:auto或

您的页脚位于“背景渐变”框内，即“位置：相对”。因此，页脚的“位置：绝对”偏移将应用于该框，而不是外部页面。使用诸如Firebug或Chrome developer工具之类的诊断工具很容易看到这些东西。我如何在后台容器中实现推式页脚呢？此外，尽管设置为100%的高度，但背景参与者由于某种原因只能伸展到目前为止。如果你想“推”页脚，那么绝对定位是没有意义的。你可能想从一个简单的测试设置开始，而且我对Firebug或Chrome开发工具一无所知。上次我开发的时候我们只有一个验证器和记事本。LOL您的页脚位于“背景渐变”框内，即“位置：相对”。因此，页脚的“位置：绝对”偏移将应用于该框，而不是外部页面。使用诸如Firebug或Chrome developer工具之类的诊断工具很容易看到这些东西。我如何在后台容器中实现推式页脚呢？此外，尽管设置为100%的高度，但背景参与者由于某种原因只能伸展到目前为止。如果你想“推”页脚，那么绝对定位是没有意义的。你可能想从一个简单的测试设置开始，而且我对Firebug或Chrome开发工具一无所知。上次我开发的时候我们只有一个验证器和记事本。LOL问题是#body元素在#footer和#footer内容下拉伸而没有正确下推。问题是#body元素在#footer和#footer内容下拉伸而没有正确下推。谢谢，是的，我现在已经删除了这些。我想我现在唯一的问题是渐变叠加，当页面延伸太远后，渐变就不再重复了。在哪个浏览器中？我穿ChromeThanks很好看，是的，我现在把这些都拿走了。我想我现在唯一的问题是渐变叠加，当页面延伸太远后，渐变就不再重复了。在哪个浏览器中？在我看来，它穿铬合金很好看
