Examples

Basic example

Use backdropInvert(n) to invert the colors showing through an element, where backdropInvert() with no argument inverts them fully:

backdropInvert(0.25)

backdropInvert()

<div mix={[...]}>
	<div mix={[...]}>
		<div mix={[backdropInvert(0.25), ...]}>backdropInvert(0.25)</div>
	</div>
	<div mix={[...]}>
		<div mix={[backdropInvert(), ...]}>backdropInvert()</div>
	</div>
</div>

Applying on a state

Wrap the call in a state utility to scope it to one selector.

u.hover(u.backdropInvert())

Responsive design

Wrap the call in a container query to scope it to one width.

u.at("md", u.backdropInvert())
