:indeterminate

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The :indeterminate CSS pseudo-class represents any form element whose state is indeterminate, such as checkboxes that have been set to an indeterminate state with JavaScript, radio buttons which are members of a group in which all radio buttons are unchecked, and elements with no value attribute.

css
/* Selects any  whose state is indeterminate */
input:indeterminate {
  background: lime;
}

Elements targeted by this selector are:

  • elements with the indeterminate property set to true.
  • elements with the same name value and none of them checked.
  • elements with no value, placing them in an indeterminate state.

Syntax

css
:indeterminate {
  /* ... */
}
