CSS - Button with transparent text

Question

In my website, I need to display a button where the background is white, and the text gets the color of the background below, which can be a solid color or a background image.

Since the background and the button location are dynamic, I can't use the solutions that where written here.

See Example below.

I'm looking for a css only solution.

Thanks for helping.

You can get this effect by adding the button's background in front of the text, using a pseudo element, and then using mix-blend-mode on the button (screen), and the pseudo element (color-burn) to create the cutout effect.

Note: this will only work if the button's background is white.

Note: mix-blend-mode is not supported by IE.

.button {
  position: relative;
  padding: 0.5em 1em;
  font-size: 1.2em;
  border: none;
  background: none;
  outline: none;
  color: black;
  mix-blend-mode: screen;
}

.button::before {
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  background: white;
  border-radius: 0.3em;
  content: '';
  mix-blend-mode: color-burn;
}

.bg {
  padding: 2em;
}

.bg1 {
  background: purple;
}

.bg2 {
  background: linear-gradient(to bottom, gold 50%, silver 50%);
}

<div class="bg bg1">
  <button class="button">Text</button>
</div>

<div class="bg bg2">
  <button class="button">Text</button>
</div>
