如何解决页脚与正文内容重叠的问题？

分类：编程问答

如何解决如何解决页脚与正文内容重叠的问题？

我的页脚与我的内容重叠（并非总是如此，我已经创建了几个以 flex/grid 为主题的 HTML 并且它们工作正常，页脚被推到它应该的位置，并且在调整页面大小时，页脚仍然可以识别内容并走得更远下）。

页脚是响应式的，宽度/高度随着浏览器窗口大小的调整而变化，因此页脚的 .px 值不起作用，我希望它没有必要。

这是代码，我将在此内容的底部包含 JSFiddle。我在 Stack Overflow 上尝试了一些问答，但似乎没有任何效果。

.a-box{

    width:200px;
    height:200px;
}

和 JSFiddle https://jsfiddle.net/f46vzgwj/

正如您在 JSFiddle 中看到的，页脚开始与内容重叠，然后完成其框，您可以看到页脚之后的最后一个内容。

解决方法

设置height: auto

.a-box{
    position:relative;
    width:200px;
    height:auto; /* this was 200px */
}
