`html/no-dupe-style-properties`

Disallow duplicate properties in inline style attributes

Default severity: warning
Presets: nuxt, opinionated
Automatic fix: None; review the suggested change
Applies to: Vue SFC templates and blocks, with script context where the rule requires it
Options: No rule-specific options. Severity and preset selection are configurable.

Configuration (Vite+)

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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "html/no-dupe-style-properties": "warn"
      }
    },
  },
});

vp run lint

Bad

Each static style repeats one property; margin and MARGIN also count as the same property.

<template>
<div style="color: red; color: blue">text</div>
<div style="margin: 0; MARGIN: 1px">text</div>
</template>

Good

The static style uses distinct color and background properties. Dynamic style bindings are outside this static-attribute check.

<template>
<div style="color: red; background: blue">text</div>
<div :style="{ color: a, color: b }">text</div>
</template>

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