<blend-mode>

Описание

The <blend-mode> type is a collection of keywords describing blend modes.

A blend mode is a method of calculating the final color value of a pixel when layers overlap. Each blend mode takes the color value of the foreground and the backdrop (top color and bottom color respectively), perfoms its calculation and returns a color value. The final, visible layer is the result of performing the blend mode calculation on every overlapping pixel among the blended layers.

Возможные значения

normal

The effect is similar to two images shone onto a projection screen.

<div id="div"></div>

#div {
    width: 300px;

    background-blend-mode: screen;
}

overlay

The final color is the result of multiply if the bottom color is darker, or screen if the bottom color is lighter.
This blend mode is equivalent to hard-light but with the layers swapped.

<div id="div"></div>

#div {
    width: 300px;
    height: 300px;

    background-blend-mode: overlay;
}

darken

The final color is a color composed of the darkest values per color channel.

    width: 300px;
    height: 300px;
    background: url('https://mdn.mozillademos.org/files/8543/br.png'),

    background-blend-mode: lighten;
}

color-dodge

The final color is the result of dividing the bottom color by the inverse of the top color.
A black foreground leads to no change. A foreground with the inverse color of the backdrop leads to a fully lit color.
This blend mode is similar to screen, but the foreground need only be as light as the inverse of the backdrop to reach a fully lit color.

<div id="div"></div>

#div {
    width: 300px;
    height: 300px;
    background: url('https://mdn.mozillademos.org/files/8543/br.png'),
                url('https://mdn.mozillademos.org/files/8545/tr.png');
    background-blend-mode: color-dodge;
}

color-burn

This final color is the result of inverting the bottom color, dividing the value by the top color, and inverting that value.
A white foreground leads to no change. A foreground with the inverse color of the backdrop leads to a black final image.
This blend mode is similar to multiply, but the foreground need only be as dark as the inverse of the backdrop to make the final image black.

<div id="div"></div>

#div {
    width: 300px;
    height: 300px;

    height: 300px;
