background-blend-mode - CSS: Cascading Style Sheets 编辑

The background-blend-mode CSS property sets how an element's background images should blend with each other and with the element's background color.

The source for this interactive example is stored in a GitHub repository. If you'd like to contribute to the interactive examples project, please clone https://github.com/mdn/interactive-examples and send us a pull request.

Blending modes should be defined in the same order as the background-image property. If the blending modes' and background images' list lengths are not equal, it will be repeated and/or truncated until lengths match.

/* Two values, one per background */

background-blend-mode: unset;
