以上是我正在尝试解决的问题的一个最小示例。它是从一个更大的页面中提取的，所以我希望可以通过 CSS 进行修复，而不是完全重新组织 DOM。

所以，.row-inner 元素上有一个剪辑路径。如果启用了剪辑路径，则 .first-section 文本显示在 body::after 背景下方，但如果禁用剪辑路径，则文本显示在 body::after 背景上方。

有没有办法让 .first-section 出现在 body::after 背景之上，并且仍然启用剪辑路径？

我从之前的问题中读到它与剪辑路径改变元素的渲染顺序有关，但在这种情况下我找不到解决问题的方法，我还没有尝试过。

如果仅通过 CSS 无法修复，那么重新排序 DOM 以修复它的最简单方法是什么？

谢谢

@floodlitworld，没问题。

【解决方案1】：

规则clip-path需要分配给more child元素。

为.row-background-inner 指定此规则，方法是将其从.row-inner 中删除。

html,
body {
    background-color: grey;
    color: white;
    position: relative;
