【问题描述】：

如何放置一个部分作为所有页面的背景？我制作了 FontAwesome 背景动画效果 所有这些都在一个部分中，我想用段落，照片，，来完成页面，并将该部分设置为所有这些的背景。 HTML 代码大约有 20 行，但我已将其缩小，以便将其放入 StackOverflow 中

【问题讨论】：

标签： html css frontend

【解决方案1】：

如果您的背景基于 DOM 元素，您不能将其应用到另一个页面，除非在另一个地方再次粘贴相同的 html 代码。但是如果你应用基于 CSS 的背景或背景图案，你可以在任何地方都使用这个。在这种情况下，您所能做的就是将该部分绝对定位在您想要的每个页面中，使用堆栈中的正确位置和 z-index。另外，需要检查页面的性能：也许一些 gif 模式会更容易。

【讨论】：

谢谢，好的建议我会记住的，,,, z-index 已经奏效了

【解决方案2】：

用 top 0 固定部分的位置，然后用 z-index 将其推回。然后将所有其他元素的背景更改为透明，并使用 z-index 将它们推到前面，这样您就可以将该部分作为整个页面的背景。
