This is a nonstandard attribute used by iOS Safari Mobile which controls whether and how the text value for textual form control descendants should be automatically capitalized as it is entered/edited by the user.
This is a nonstandard attribute used by iOS Safari Mobile which controls whether and how the text value for textual form control descendants should be automatically capitalized as it is entered/edited by the user. If the
autocapitalize attribute is specified on an individual form control descendant, it trumps the form-wide
autocapitalize setting. The non-deprecated values are available in iOS 5 and later. The default value is
sentences. Possible values are:
none: Completely disables automatic capitalizationsentences: Automatically capitalize the first letter of sentences.words: Automatically capitalize the first letter of words.characters: Automatically capitalize all characters.on: Deprecated since iOS 5.off: Deprecated since iOS 5.
Indicates whether input elements can by default have their values automatically completed by the browser.
Indicates whether input elements can by default have their values automatically completed by the browser. This setting can be overridden by an
autocomplete attribute on an element belonging to the form. Possible values are:
off: The user must explicitly enter a value into each field for every use, or the document provides its own auto-completion method; the browser does not automatically complete entries.on: The browser can automatically complete values based on values that the user has previously entered in the form.
For most modern browsers (including Firefox 38+, Google Chrome 34+, IE 11+) setting the autocomplete attribute will not prevent a browser's password manager from asking the user if they want to store login (username and password) fields and, if they agree, from autofilling the login the next time the user visits the page.

A name or keyword indicating where to display the response that is received after submitting the form.
A name or keyword indicating where to display the response that is received after submitting the form. In HTML 4, this is the name/keyword for a frame. In HTML5, it is a name/keyword for a browsing context (for example, tab, window, or inline frame). The following keywords have special meanings:
_self: Load the response into the same HTML 4 frame (or HTML5 browsing context) as the current one. This value is the default if the attribute is not specified._blank: Load the response into a new unnamed HTML 4 window or HTML5 browsing context._parent: Load the response into the HTML 4 frameset parent of the current frame, or HTML5 parent browsing context of the current one. If there is no parent, this option behaves the same way as _self._top: HTML 4: Load the response into the full original window, and cancel all other frames. HTML5: Load the response into the top-level browsing context (i.e., the browsing context that is an ancestor of the current one, and has no parent).
