HTML Guides for autocorrect

The autocorrect attribute on <input> elements does not accept "none" as a valid value. The correct value to disable autocorrection is "off".

The autocorrect attribute controls whether the browser should automatically correct text input. It accepts only two values: "on" to enable autocorrection and "off" to disable it. The value "none" is not part of the specification and will fail W3C validation.

This attribute was originally a non-standard Safari extension, but it has since been added to the HTML standard. It applies to <input> elements that accept text input (such as text, search, and url types), <textarea> elements, and elements with contenteditable set.

Note that autocorrect is different from autocomplete, which uses "off" and "on" as well, but also accepts many other token values like "name" or "email". The two attributes control different behaviors: autocorrect handles spelling correction, while autocomplete handles previously entered values and autofill.
