CSS Text color difference based on background

Traditional CSS is quite lame; it only allows us to set 1 color for the text. But seeing we create more and more floating and fixed elements, we might want to have a dynamic text-color.

How to create a difference based text color in CSS permalink

Let's start by marking up the html:

<div class="text-container">
  <h1>Difference</h1>
</div>
<section></section>
<section></section>

Then we want to include two random backgrounds for the sections. Let's do that.

section {
  width: 100vw;
  height: 100vh;
  background: #000;
  &:nth-child(odd) {
    background: #fff;
  }
}

And make sure the text div is floating on top of everything!

.text-container {
  position: fixed;
  width: 100vw;
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
  color: #fff;
  mix-blend-mode: difference;
  h1 {
    font-size: 150px;
  }
}

We included mix-blend-mode: difference; this makes the color blend based on the background.

Awesome, right?! 🤩

This also works on images/videos backgrounds and whatnot!

Browser support permalink

Unfortunately not supported by IE, but still overall good support! I use this option a lot to make just that small difference!
