使文本 <div> 适合带有剪辑路径的标题图像

Question

我有一个标题图像，它使用剪辑路径使其下部倾斜，如下所示：

CSS：

.angled {
  -webkit-clip-path: polygon(0 0, 100% 0, 100% 100%, 0 96%);
  clip-path: polygon(0 0, 100% 0, 100% 100%, 0 96%);
}

然后我将这个类应用到任何我想要有角度的 div 上，这很有效，但是对于该类中包含文本的 div，文本不适合新形状的 div。我想要它，所以第一行 - 大标题，正好适合这个角度。

（请注意，使用 codepen，由于某种原因视频不会剪辑 - 它在本地可以正常工作 - 这不是问题）

这是我的codepen

.angled {
  -webkit-clip-path: polygon(0 0, 100% 0, 100% 100%, 0 80%);
  clip-path: polygon(0 0, 100% 0, 100% 100%, 0 80%);
}

.angled-inverted {
  -webkit-clip-path: polygon(0 0, 100% 0, 100% 80%, 0 100%);
  clip-path: polygon(0 0, 100% 0, 100% 80%, 0 100%);
}


header {
  position: relative;
  background-color: black;
  height: 75vh;
  min-height: 25rem;
  width: 100%;
  overflow: hidden;
}

header video {
  position: absolute;
  top: 50%;
  left: 50%;
  min-width: 100%;
  min-height: 100%;
  width: auto;
  height: auto;
  z-index: 0;
  -ms-transform: translateX(-50%) translateY(-50%);
  -moz-transform: translateX(-50%) translateY(-50%);
  -webkit-transform: translateX(-50%) translateY(-50%);
  transform: translateX(-50%) translateY(-50%);
}

header .container {
  position: relative;
  z-index: 2;
}

header .overlay {
  position: absolute;
  top: 0;
  left: 0;
  height: 100%;
  width: 100%;
  background-color: black;
  opacity: 0.5;
  z-index: 1;
}

@media (pointer: coarse) and (hover: none) {
  header {
    background: url('https://source.unsplash.com/XT5OInaElMw/1600x900') black no-repeat center center scroll;
  }
  header video {
    display: none;
  }
}

Answer 1

clip path 不受支持，用于图像而非文本，
如果您设置严格的字体大小，则它不能自行更改，
padding 不能为负数，
不应使用单位 pt
最后你将 css 到处传播——外部的、内联的、相互争论的多个子层 以上任何一种都会导致问题。
