如何根据一侧的背景图像添加三角形边框(垂直)?

How to add a triangled border (vertically) respecting the background image of one side?

我在 CSS 中制作了一个垂直横幅,我想创建两个区域。

分隔线应该是三角形。一侧有背景,"triangle shape" 应保留该背景。

最好用图片解释 ;-)

我正要这样做,但是一个形状一直持续到最后...我卡住了。

.box {
  background-image: 
    linear-gradient(195deg, transparent 70%, #000 70%, #000 71%, #fff 71%), 
    linear-gradient(165deg, transparent 70%, #000 70%, #000 71%, #fff 71%),

  background-position: top, center;
  background-size: 250px 100%, cover;
  background-repeat: no-repeat;
}
<div class="box">
  some text here<br> more text
</div>

您可以这样调整代码:

.box {
  padding: 50px 30px;
  height:300px;
  width:100px;
  text-align: right;
  background-image:
    linear-gradient(200deg,transparent 70%,#000 70%,#000 71%,#fff 71%),
    linear-gradient(160deg,transparent 70%,#000 70%,#000 71%,#fff 71%),

  background-position:bottom left,bottom right,center;
  background-size:50% 600px,50% 600px,cover;
  background-repeat:no-repeat;
  
  display:flex;
  align-items:flex-end;
}
<div class="box">
  some text here<br> more text
</div>
