Examples

Basic example

Use utilities like contrast-50 and contrast-100 to control an element's contrast:

contrast-50

contrast-100

contrast-125

contrast-200

<img class="contrast-50 ..." src="/img/mountains.jpg" /><img class="contrast-100 ..." src="/img/mountains.jpg" /><img class="contrast-125 ..." src="/img/mountains.jpg" /><img class="contrast-200 ..." src="/img/mountains.jpg" />

Using a custom value

Use the contrast-[<value>] syntax to set the contrast based on a completely custom value:

<img class="contrast-[.25] ..." src="/img/mountains.jpg" />

For CSS variables, you can also use the contrast-(<custom-property>) syntax:

<img class="contrast-(--my-contrast) ..." src="/img/mountains.jpg" />

This is just a shorthand for contrast-[var(<custom-property>)] that adds the var() function for you automatically.

Responsive design

Prefix a filter: contrast() utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:

<img class="contrast-125 md:contrast-150 ..." src="/img/mountains.jpg" />
