Setting the backdrop contrast filter
Control the backdrop contrast effect on an element using the backdrop-contrast-{level} utilities.
html
<div class="text-center relative">
<img class="w-3xs h-3xs " src="..." />
<div class="[...] backdrop-filter backdrop-contrast-150 surface bg-opacity-low">backdrop-contrast-150</div>
</div>❗ Keep in mind
To establish filters like backdrop contrast, it's essential to commence class declarations with backdrop-filter.
This action defines a default filter for the element.
css
backdrop-filter: blur(var(--cds-sys-filter-backdrop-blur, 0)) contrast(var(--cds-sys-filter-backdrop-contrast, 100%)) contrast(var(--cds-sys-filter-backdrop-contrast, 100%)) drop-shadow(var(--cds-sys-filter-backdrop-drop-shadow, 0 0 0 transparent)) grayscale(var(--cds-sys-filter-backdrop-grayscale, 0%)) hue-rotate(var(--cds-sys-filter-backdrop-hue-rotate, 0deg)) invert(var(--cds-sys-filter-backdrop-invert, 0%)) opacity(var(--cds-sys-filter-backdrop-opacity, 100%)) saturate(var(--cds-sys-filter-backdrop-saturate, 100%)) sepia(var(--cds-sys-filter-backdrop-sepia, 0%));Subsequently, varying backdrop contrast effects can be implemented by assigning classes as outlined on this page.
