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

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:

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.


:autofill {
  /* ... */


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. For the best browser compatibility use both :-webkit-autofill and :autofill.

input {
  border: 3px solid grey;
  border-radius: 3px;

input:-webkit-autofill {
  border: 3px solid blue;
input:autofill {
  border: 3px solid blue;
<form method="post" action="">
  <label for="email">Email</label>
  <input type="email" name="email" id="email" autocomplete="email" />
