Solving the mix-blend-mode Issue in CSS

When working with advanced CSS techniques, you may encounter problems that seem perplexing, particularly when combining CSS properties like mix-blend-mode and transform. One such scenario is when you want to make text "transparent" to reveal content underneath, but find that your styling behaves unexpectedly when applying a transform to the parent container. In this guide, we'll explore the problem and provide a clear solution to get your design back on track.

The Problem

In a recent case, a developer faced a frustrating challenge: their button text, which was supposed to use mix-blend-mode: screen; to create a transparent effect, only worked when the transform property was removed from the parent div. This leaves many asking the question: Why does transform disrupt the functioning of mix-blend-mode?

The root of this issue stems from how blending and transformations interact in the CSS stacking context. When a transformed element is created, a new stacking context is formed, which can lead to unexpected rendering of blend modes that depend on how layers are visually stacked and combined.

How to Fix the Issue

Fortunately, there is a way to resolve this issue while retaining both the desired transformation and blend effects! Follow these structured steps to adjust your CSS and HTML:

Step 1: Update Your CSS

Instead of applying mix-blend-mode to the button, move it to the parent container. Here’s how your CSS code should look:

Implementing these fixes will ensure that your text remains transparent and blends seamlessly with the background content, fulfilling your design needs.
