autocapitalize

The autocapitalize global attribute is an enumerated attribute that controls whether inputted text is automatically capitalized and, if so, in what manner. This is relevant to:

<input> and <textarea> elements.
Any element with contenteditable set on it.

autocapitalize doesn't affect behavior when typing on a physical keyboard. It affects the behavior of other input mechanisms such as virtual keyboards on mobile devices and voice input. This can assist users by making data entry quicker and easier, for example by automatically capitalizing the first letter of each sentence.

Value

Possible values are:

none or off: Do not automatically capitalize any text.
sentences or on: Automatically capitalize the first character of each sentence.
words: Automatically capitalize the first character of each word.
characters: Automatically capitalize every character.

Usage notes

autocapitalize can be set on <input> and <textarea> elements, and on their containing <form> elements. When autocapitalize is set on a <form> element, it sets the autocapitalize behavior for all contained <input>s and <textarea>s, overriding any autocapitalize values set on contained elements.
autocapitalize has no effect on the url, email, or password <input> types, where autocapitalization is never enabled.
Where autocapitalize is not specified, the adopted default behavior varies between browsers. For example:
- Chrome and Safari default to on/sentences
- Firefox defaults to off/none.
