A practical guide to replacing CSS !important with cleaner alternatives. Covers how specificity and source order work, why !important causes maintenance problems in larger projects, and several alternatives: cascade layers for explicit priority groups, the :is() pseudo-class for bumping specificity, selector doubling, and smarter stylesheet ordering. Also clarifies legitimate use cases for !important such as utility classes, third-party overrides, user stylesheets, and accessibility-related media queries like prefers-reduced-motion.
