粘性页脚覆盖主体内容

Question

我正在尝试制作一个带有粘性页脚的网页，但是当正文内容足够长时，页脚会与内容重叠。你能告诉我如何解决这个问题吗？我已经尝试了大约 5 种不同的 "sticky footer" 脚本，但每一种都不起作用。

谢谢！

Answer 1

在您的示例中，您必须在 HTML 中将 </headerwrap> 更改为 </div>，并在 CSS 中将 footer 更改为 position: fixed; .

Answer 2

将您的位置更改为相对，我在内容和页脚之间的内容之间添加了额外的 div - 'push' div Output

html {

  min-height: 100%;

body {
  margin: 0 0 170px;

  min-height: 100%;
}
#push {
  height: 170px;
}
footer {
