The background-clip Property

The background-clip property determines how a background fill or background image will be placed relative to the element: under the border, only inside the padding, or only over the content.

Features

• When using border-box with transparent borders, the background will be visible beneath them
• The text value requires vendor prefixes for full support
• The property works with gradients and multiple backgrounds
• With border-radius, the background is clipped to the rounded corners

Browser Support

All modern browsers support border-box, padding-box, and content-box. The text value requires the -webkit- prefix and is supported in Chrome, Safari, Edge.

Syntax

cssselector {
  background-clip: border-box | padding-box | content-box | text;
}

Values

Default value: border-box.

Example . border-box value

The background extends under the semi-transparent border:

html<div id="elem"></div>

css#elem {
  background-clip: border-box;
  background-color: #ffd6d6;
  background-repeat: no-repeat;
  border: 10px dashed rgba(0,0,0,0.3);
  padding: 30px;
  width: 250px;
  height: 150px;
}

Результат:

html<div id="elem"></div>

css#elem {
  background-clip: padding-box;
  background-color: #ffd6d6;
  background-repeat: no-repeat;
  border: 10px dashed rgba(0,0,0,0.5);
  padding: 30px;

html<div id="elem">
  text text text text text
  text text text text text
  text text text text text
</div>

css#elem {
  background-clip: content-box;
  background-color: #ffd6d6;

  border: 10px dashed rgba(0,0,0,0.3);

html<div id="elem">text text text</div>

css#elem {
  display: inline-block;
  background: linear-gradient(to right, red, blue);
  -webkit-background-clip: text;
  -webkit-text-fill-color: transparent;
