CSS Mix Blend Mode Reference

In the world of web design, CSS provides a powerful set of tools for creating visually engaging websites. One such tool is the CSS mix-blend-mode, which allows developers to control how elements blend together. This article will serve as a comprehensive reference for beginners, exploring the concept of blend modes, their usage, and providing examples to illustrate their practical applications.

1. Introduction

The mix-blend-mode property in CSS specifies how an element’s content should blend with the content of the element’s parent and the background. This mixing of colors and images can add depth and visual interest to pages, making them more engaging for users. Understanding how to effectively use these blending modes is essential for any web designer looking to elevate their craft.

2. What is Mix Blend Mode?

Mix blend mode is a property that determines how the content of an element is blended with its background. While traditional blending uses techniques such as overlays and combines aspects of images, mix-blend-mode works directly within the CSS environment.

It differs from other blending techniques by allowing multiple background layers to interact not only with each other but also with the foreground elements, creating a dynamic visual experience.

3. Browser Support

The mix-blend-mode property is widely supported in modern browsers, but it is essential to check compatibility when working on projects intended for a specific audience. Below is a table indicating browser support:

Browser	Supported Version
Chrome	Version 76+
Firefox	Version 63+
Safari	Version 12.1+
Edge	Version 16+
Opera	Version 63+

4. Usage

To use the mix-blend-mode property in CSS, you apply it to an element. The basic syntax is as follows:

.element {
    mix-blend-mode: ;
}
    

Here’s a simple example of how to apply a blend mode:

div {
    background-color: red;
    width: 200px;
    height: 200px;
    position: relative;
}

.overlay {
    position: absolute;
    top: 0;
    left: 0;
    width: 200px;
    height: 200px;
    mix-blend-mode: multiply;
    background-color: blue;
}
    

5. Values

CSS offers several blend mode values, each producing a different visual effect. Here is an overview:

Blend Mode	Description
normal	No blending occurs; the content is displayed as is.
multiply	Multiplies the base color with the blend color, resulting in darker colors.
screen	Inverts the colors, multiplies them, and inverts them again, resulting in lighter colors.
overlay	Combines multiply and screen modes; dark colors become darker, light colors become lighter.
darken	Keeps the darker colors from the two elements.
lighten	Keeps the lighter colors from the two elements.
color-dodge	Brightens the base color to reflect the blend color.
color-burn	Darkens the base color to reflect the blend color.
hard-light	Uses the blend color to affect the brightness of the base color.
soft-light	Darkens or lightens the color based on the blend color, producing softer results.
difference	Subtracts the blend color from the base color and vice versa; results in high-contrast images.
exclusion	Similar to difference but with lower contrast.
hue	Preserves luminance and saturation, modifying only the hue.
saturation	Preserves hue and luminance, modifying only the saturation.
color	Preserves luminance while changing the hue and saturation.
luminosity	Preserves hue and saturation, modifying only luminance.
