Mix‑Blend‑Mode Playground - Online CSS Effect Tester

CSS mix-blend-mode defines how an element's content should blend with the content of its parent element and the element's background. It works similarly to blend modes in Photoshop or other graphic design tools, allowing you to create stunning overlay effects, color manipulations, and artistic compositions directly in the browser with no image editing required.

All modern browsers support mix-blend-mode — Chrome (41+), Firefox (32+), Safari (8+), and Edge (79+). It has excellent coverage of over 96% of global web users. However, it is not supported in Internet Explorer. For IE compatibility, consider using background-blend-mode on a single element with multiple backgrounds as a fallback approach.

mix-blend-mode blends an entire element (including its content, text, and children) with whatever is behind it. background-blend-mode blends multiple background layers on a single element together, but does not affect text or child elements. Use mix-blend-mode when you want layered elements to interact; use background-blend-mode when working with multiple backgrounds on one element.

Double exposure is typically achieved using mix-blend-mode: screen or lighten. Place a portrait image as the bottom layer and a landscape or texture image as the top layer with the blend mode applied. Set the top layer's opacity to around 0.7–0.9 for a subtle, ethereal double exposure effect. You can experiment with overlay and soft-light for different artistic variations.

Common reasons include: (1) The blending element has no content behind it — mix-blend-mode needs a backdrop to blend with. Ensure the parent or underlying elements have visible content. (2) The parent has isolation: isolate set, which creates a new stacking context that prevents blending with elements further behind. (3) The element or its parent has a solid background-color that overrides the blend. (4) The element is inside a container with transform, opacity < 1, or will-change that creates a new stacking context.

Yes! mix-blend-mode works beautifully on text elements. This is a popular technique for creating dynamic, readable headlines that adapt to background images or videos. Apply it directly to a <h1> or <span> element — the text color will blend with whatever is behind it. difference mode on white text creates an especially striking effect where text becomes visible over both light and dark areas.

Generally, mix-blend-mode has minimal performance impact for most use cases. Modern browsers handle blending using GPU acceleration. However, applying blend modes to large, animating elements or many elements simultaneously (50+) may cause noticeable performance degradation, especially on mobile devices. For best performance, avoid animating blended elements and limit the number of active blend layers on a page.

Multiply is great for darkening and creating depth (shadows, overlays). Screen brightens and is perfect for light leaks and glowing effects. Overlay boosts contrast and saturation — ideal for photo enhancements. Difference creates striking, high-contrast artistic effects. Soft-light gives a subtle, natural lighting effect. Color is used to tint images while preserving their luminance. Each mode has its own character — this playground helps you discover which works best for your design.

Yes! You can stack multiple elements, each with its own mix-blend-mode. The blending happens in order from bottom to top — each layer blends with the composite result of all layers below it. This allows for complex, multi-layered compositions. You can also combine mix-blend-mode with CSS filters (filter: brightness(), contrast(), etc.) for even more creative control.

Yes, CSS mix-blend-mode uses the same mathematical formulas as Photoshop's blend modes (as defined by the W3C Compositing and Blending specification). The 16 modes — Multiply, Screen, Overlay, Darken, Lighten, Color-Dodge, Color-Burn, Hard-Light, Soft-Light, Difference, Exclusion, Hue, Saturation, Color, and Luminosity — behave identically to their Photoshop counterparts, making it easy for designers to translate their knowledge from graphic design to web development.
