:user-invalid - CSS | MDN
Toggle sidebar
:user-invalid
Baseline
2023
Newly available
Since November 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
The :user-invalid CSS pseudo-class represents any validated form element whose value isn't valid based on their validation constraints, after the user has interacted with it.
The :user-invalid pseudo-class must match an :invalid, :out-of-range, or blank-but :required element between the time the user has attempted to submit the form and before the user has interacted again with the form element.
Syntax
css
:user-invalid {
/* ... */
}
Examples
Setting a color and symbol on :user-invalid
In the following example, the red border and ❌ only display once the user has interacted with the field. Try typing something other than an email address to see it in action.
html
<form>
<label for="email">Email *: </label>
<input id="email" name="email" type="email" required />
<span></span>
</form>
css
input:user-invalid {
border: 2px solid red;
}
input:user-invalid + span::before {
content: "✖";
color: red;
}
