      This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2020.
The :read-write CSS pseudo-class represents an element (such as input or textarea) that is editable by the user.
Try it
label,
input[type="submit"] {
  display: block;
  margin-top: 1em;
}
*:read-write {
  background-color: ivory;
  border: 2px solid darkorange;
  border-radius: 5px;
}
<p>Please fill in your details:</p>
<form>
  <label for="email">Email Address:</label>
  <input id="email" name="email" type="email" value="test@example.com" />
  <label for="note">Short note about yourself:</label>
  <textarea id="note" name="note">Don't be shy</textarea>
  <label for="pic">Your picture:</label>
  <input id="pic" name="pic" type="file" />
  <input type="submit" value="Submit form" />
</form>
Syntax
:read-write {
  /* ... */

Examples
>Confirming form details using read-only controls
You can use readonly form controls when you want a user to verify information they entered earlier, which you want to submit with new data in read-write controls.
In the example below, the :read-only pseudo-class is used to make the <textarea> (a user's address) look like a regular paragraph. The :read-write pseudo-class provides a way to highlight the editable <textarea> (the delivery instructions):
textarea:read-only {
  border: 0;
}
textarea:read-write {
  box-shadow: inset 1px 1px 3px #cccccc;
  border-radius: 5px;
}
<form>
  <fieldset>
    <legend>Confirm details</legend>
    <div>
      <label for="address">Address:</label>
      <textarea id="address" name="address" readonly>
123 Choco Mountain,
Awesome Ridge,
CA</textarea
      >
    </div>
    <div>
      <label for="instructions">Delivery instructions</label>
      <textarea id="instructions" name="instructions"></textarea>
    </div>
  </fieldset>
  <button type="submit">Confirm</button>
</form>
Styling read-write non-form controls
This selector doesn't just select <input>/<textarea> elements — it will select any element that can be edited by the user, such as a <p> element with contenteditable set on it.
<p contenteditable>This paragraph is editable; it is read-write.</p>
<p>This paragraph is not editable; it is read-only.</p>
body {
  font-family: sans-serif;
}
p {
  font-size: 150%;
  padding: 5px;
  border-radius: 5px;
}
p:read-only {
  background-color: red;
  color: white;
}
p:read-write {
  background-color: lime;
}
