The autocorrect attribute is a global HTML attribute used to control whether the browser or device should automatically correct text input in certain elements, typically <input> or <textarea>. It is primarily intended for touch-based devices, like smartphones and tablets, where software keyboards often offer automatic spelling correction. While autocorrect is not part of the official HTML specification, it is widely supported on mobile browsers (especially iOS Safari).

Purpose

The attribute allows web developers to enable or disable automatic text corrections, giving users the freedom to either rely on the device’s spelling suggestions or type freely without interference. This can be useful for fields like usernames, passwords, code snippets, or specialized terminology where autocorrection could be disruptive.

Usage

The autocorrect attribute can be added to any HTML element that accepts user input, including:

• <input type="text">
• <input type="search">
• <textarea>

Example

<form>
  <!-- Autocorrect enabled (default behavior on some devices) -->
  <label for="note">Notes:</label>
  <textarea id="note" name="note" autocorrect="on"></textarea>

  <!-- Autocorrect disabled -->
  <label for="username">Username:</label>
  <input type="text" id="username" name="username" autocorrect="off">
</form>

In this example:

• The textarea for note allows the device to suggest and automatically correct spelling errors.
• The input for username disables autocorrection, which is important for usernames that may contain unusual characters or capitalization.

Notes

• The attribute is case-insensitive, meaning "on" and "ON" behave the same.
• It is often used alongside other text input attributes like spellcheck="true" or autocomplete to create a more controlled input experience.
• Not all devices respect the autocorrect setting, so behavior may vary slightly between browsers and platforms.
