revertBaseline · Widely available
The revert CSS keyword resets any property to its previous default, provided by either the user or browser stylesheets. For example, setting display: revert on a <div> will likely result in display: block, the browser default style. This is often confused with initial.
Supported in all major browsers for at least 30 months — safe to use without fallbacks. Baseline since Jul 27, 2020. Widely available since Jan 27, 2023.
