Contrast
Utilities for applying contrast filters to an element.
Quick reference
Class | Properties |
---|---|
contrast-0 | filter: contrast(0); |
contrast-50 | filter: contrast(.5); |
contrast-75 | filter: contrast(.75); |
contrast-100 | filter: contrast(1); |
contrast-125 | filter: contrast(1.25); |
contrast-150 | filter: contrast(1.5); |
contrast-200 | filter: contrast(2); |
Basic usage
Changing element contrast
Use the contrast-*
utilities to control an element’s contrast.
contrast-50
contrast-100
contrast-125
contrast-200
<div class="contrast-50 ...">
<!-- ... -->
</div>
<div class="contrast-100 ...">
<!-- ... -->
</div>
<div class="contrast-125 ...">
<!-- ... -->
</div>
<div class="contrast-200 ...">
<!-- ... -->
</div>
Removing filters
To remove all of the filters on an element at once, use the filter-none
utility:
<div class="blur-md invert contrast-125 md:filter-none">
<!-- ... -->
</div>
This can be useful when you want to remove filters conditionally, such as on hover or at a particular breakpoint.
Applying conditionally
Hover, focus, and other states
Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:contrast-150
to only apply the contrast-150
utility on hover.
<div class="contrast-125 hover:contrast-150">
<!-- ... -->
</div>
For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.
Breakpoints and media queries
You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:contrast-150
to apply the contrast-150
utility at only medium screen sizes and above.
<div class="contrast-125 md:contrast-150">
<!-- ... -->
</div>
To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.
Using custom values
Customizing your theme
By default, Tailwind includes a handful of general purpose contrast
utilities. You can customize these values by editing theme.contrast
or theme.extend.contrast
in your tailwind.config.js
file.
module.exports = {
theme: {
extend: {
contrast: {
25: '.25',
}
}
}
}
Learn more about customizing the default theme in the theme customization documentation.
Arbitrary values
If you need to use a one-off contrast
value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.
<div class="contrast-[.25]">
<!-- ... -->
</div>
Learn more about arbitrary value support in the arbitrary values documentation.
