Tailwind CSS Backdrop Contrast

The backdrop-contrast utility class in Tailwind CSS is used to apply contrast to the backdrop of an element. This class is commonly used in combination with the backdrop-filter class to create effects like blur, brightness, and contrast.

Syntax

The syntax for using the backdrop-contrast class is as follows:

<div class="backdrop-contrast-{amount}"></div>

• {amount}: This is a number between 0 and 100, representing the percentage of contrast to be applied to the backdrop. The default value is 100.

Example

Here is an example of using the backdrop-contrast class to apply contrast to a backdrop:

<div class="relative">
  <img src="img.jpg" alt="Image">
  <div class="absolute inset-0 bg-black bg-opacity-50 backdrop-filter backdrop-contrast-150"></div>
  <div class="absolute inset-0 flex items-center justify-center">
    <h1 class="text-white text-4xl font-bold">Hello World</h1>
  </div>
</div>

In this example, we have an image with a text overlay. We are using the backdrop-contrast-150 class to apply a 150% contrast to the backdrop along with the backdrop-filter class to create a blurry effect.

Output

The backdrop-contrast class applies contrast to the backdrop of an element. In the example above, we are using it to create a dark overlay behind the text, thus increasing the contrast between the text and the background.
