Create a Responsive Slanted Edge for a Div

Problem:

Creating a slanted edge for a div without using borders that will obscure underlying images.

Solution:

Slanted Pseudo Element:

Utilize a skewed pseudo element to create the slanted background while preserving the text content above it.

Transform Origin:

Set the transform origin of the pseudo element to the desired anchor point for the slant (right bottom corner in this case).

Skew Transformation:

Apply a skew transformation to the pseudo element to angle it accordingly (e.g., -45 degrees).

Overflow:

Use overflow: hidden; to hide any overflowing parts of the pseudo element.

Negative Z-Index:

Position the pseudo element behind the div content using a negative z-index.

Example Code:

div {
  position: relative;
  display: inline-block;
  padding: 1em 5em 1em 1em;
  overflow: hidden;
  color: #fff;
}

div:after {
  content: '';
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background: #000;
  -webkit-transform-origin: 100% 0;
  -ms-transform-origin: 100% 0;
  transform-origin: 100% 0;
  -webkit-transform: skew(-45deg);
  -ms-transform: skew(-45deg);
  transform: skew(-45deg);
  z-index: -1;
}

body {
  background: url('https://farm3.staticflickr.com/2878/10944255073_973d2cd25c.jpg');
  background-size: cover;
}

Result:
