Validator

Validator styles native HTML validity using rules such as required, pattern and min/max. Associate errors and validate again on the server; browser validity does not prove server acceptance.

Installation and initialization

npm install -D tailwindcss@4.2.1 @tailwindcss/cli@4.2.1 daisyui@5.7.47

This is a native CSS plugin, not a React component import. Build Tailwind 4 with the daisyUI plugin and load the generated stylesheet before copying an example. See the included setup guide; do not override an existing project's React or Tailwind versions blindly.

@import "tailwindcss";
@plugin "daisyui" { themes: light --default, dark --prefersdark; }

Source and executable behavior

Source files preserve the original code fences, including original comments and demo strings. The $$ class prefix placeholder must be resolved for your plugin configuration: without a prefix, $$btn becomes btn. Copy every listed source file for the chosen example, combine HTML/CSS/JS appropriately and implement native events. The preview's reviewed event adapters are not a backend or an automatically installed application runtime.

Complete first example

<input class="$$input $$validator" type="email" required placeholder="mail@site.com" />

Theme, accessibility and verification

Use native data-theme boundaries. Verify keyboard operation, labels, visible focus, disabled/invalid states where applicable, light/dark, mobile and reduced motion. Check your target browser's dialog, popover and CSS feature support. CSS classes do not supply unimplemented JavaScript or business services. Clean up timers and third-party instances; copying a command is not installation success.
