Web/HTML/Global attributes/autocapitalize

The autocapitalize global attribute is an enumerated attribute that controls whether and how text input is automatically capitalized as it is entered/edited by the user. The attribute must take one of the following values:

off or none: No autocapitalization is applied (all letters default to lowercase)
on or sentences: The first letter of each sentence defaults to a capital letter; all other letters default to lowercase
words: The first letter of each word defaults to a capital letter; all other letters default to lowercase
characters: All letters should default to uppercase

The autocapitalize attribute doesn’t affect behavior when typing on a physical keyboard. Instead, it affects the behavior of other input mechanisms, such as virtual keyboards on mobile devices and voice input. The behavior of such mechanisms is that they often assist users by automatically capitalizing the first letter of sentences. The autocapitalize attribute enables authors to override that behavior per-element.

The autocapitalize attribute never causes autocapitalization to be enabled for an <input> element with a type attribute whose value is url, email, or password.
