Styling Form State

You can form elements based on their state without conditional logic.

<input
  class="rounded-md bg-white px-3 py-1.5 outline-2 outline-slate-400 invalid:outline-red-500 disabled:cursor-not-allowed disabled:bg-gray-100"
/>

Available Variants

  • required:
  • invalid: / valid:: Input validation state.
  • user-invalid: and user-valid:: Checks validity after the user has interacted with the input.
  • in-range: and out-of-range:: For use with number inputs
  • disabled: and enabled:
  • read-only:: Inputs that are… read only.
  • checked:: Checkboxes/radios
  • indeterminate:: Partial selection with checkboxes.
  • optional:: Non-required fields.
  • placeholder-shown:: Styles for when the placeholder is visible.
  • autofill:: Inputs that the browser has automattically filled.
  • focus: / focus-visible: / focus-within:: Focus states
