:autofill

Baseline 2023
Newly available

Since February 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The :autofill CSS pseudo-class matches when an <input> element has its value autofilled by the browser. The class stops matching if the user edits the field.

Try it

label {   display: block;   margin-top: 1em; }  input:is(:-webkit-autofill, :autofill) {   border: 3px solid darkorange; } 
<form>   <p>Click on the text box and choose any option suggested by your browser.</p>    <label for="name">Name</label>   <input id="name" name="name" type="text" autocomplete="name" />    <label for="email">Email Address</label>   <input id="email" name="email" type="email" autocomplete="email" />    <label for="country">Country</label>   <input id="country" name="country" type="text" autocomplete="country-name" /> </form>

Note: The user agent style sheets of many browsers use !important in their :-webkit-autofill style declarations, making them non-overridable by webpages without resorting to JavaScript hacks. For example Chrome has the following in its internal stylesheet:

css
background-color: rgb(232 240 254) !important; background-image: none !important; color: -internal-light-dark(black, white) !important;

This means that you cannot set the background-color, background-image, or color in your own rules.

Syntax

css
:autofill {   /* ... */ }

Examples

The following example demonstrates the use of the :autofill pseudo-class to change the border of a text field that has been autocompleted by the browser. To ensure we don't create an invalid selector list, both :-webkit-autofill and :autofill are matched using a forgiving selector list with :is().

css
input {   border-radius: 3px; }  input:is(:-webkit-autofill, :autofill) {   border: 3px dotted orange; }
html
<form method="post" action="">   <label for="email">Email</label>   <input type="email" name="email" id="email" autocomplete="email" /> </form>
