How to Create a Slanted Background Using CSS Pseudo Elements?

Creating Slanted Backgrounds with CSS

Creating a slanting background can be achieved using a variety of CSS styling options. One effective approach involves utilizing pseudo elements along with skew transformations.

Implementation with CSS Pseudo Element

The following CSS code demonstrates how to create a slanting background using a pseudo element:

body {
  height: 100vh;
  margin: 0;
  background: yellow;
}

body:before {
  content: "";
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  width: 300px;
  background: #000;
  transform: skew(-30deg);
  transform-origin:top;
}

This code creates a斜斜背景 located on the left side of the container. The transform: skew(-30deg) property tilts the pseudo element, resulting in the desired slant.
