Configuration (Vite+)

import { defineConfig } from "@vizejs/vite-plugin/vite-plus";

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "css/no-important": "warn"
      }
    },
  },
});

vp run lint

Bad

The color declaration overrides normal cascade priority with !important.

<style scoped>
.button {
  color: red !important;
}
</style>

Good

The color comes from a custom property without an important declaration.

<style scoped>
.button {
  color: var(--button-color);
}
</style>

Good avoids this rule's finding under the configuration above; other rules may still report diagnostics.
