<form>: The Form element
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The <form>
HTML element represents a document section containing interactive controls for submitting information.
Try it
It is possible to use the :valid
and :invalid
CSS pseudo-classes to style a <form>
element based on whether the elements
inside the form are valid.
Attributes
This element includes the global attributes.
accept
Deprecated-
Comma-separated content types the server accepts.
Note: This attribute has been deprecated and should not be used. Instead, use the
accept
attribute on<input type=file>
elements. accept-charset
-
Space-separated character encodings the server accepts. The browser uses them in the order in which they are listed. The default value means the same encoding as the page. (In previous versions of HTML, character encodings could also be delimited by commas.)
autocapitalize
-
Controls whether inputted text is automatically capitalized and, if so, in what manner. See the
autocapitalize
global attribute page for more information. autocomplete
-
Indicates whether input elements can by default have their values automatically completed by the browser.
autocomplete
attributes on form elements override it on<form>
. Possible values:off
: The browser may not automatically complete entries. (Browsers tend to ignore this for suspected login forms; see Managing autofill for login fields.)on
: The browser may automatically complete entries.
name
-
The name of the form. The value must not be the empty string, and must be unique among the
form
elements in the forms collection that it is in, if any. rel
-
Controls the annotations and what kinds of links the form creates. Annotations include
external
,nofollow
,opener
,noopener
, andnoreferrer
. Link types includehelp
,prev
,next
,search
, andlicense
. Therel
value is a space-separated list of these enumerated values.
Attributes for form submission
The following attributes control behavior during form submission.
action
-
The URL that processes the form submission. This value can be overridden by a
formaction
attribute on a<button>
,<input type="submit">
, or<input type="image">
element. This attribute is ignored whenmethod="dialog"
is set. enctype
-
If the value of the
method
attribute ispost
,enctype
is the MIME type of the form submission. Possible values:application/x-www-form-urlencoded
: The default value.multipart/form-data
: Use this if the form contains<input>
elements withtype=file
.text/plain
: Useful for debugging purposes.
This value can be overridden by
formenctype
attributes on<button>
,<input type="submit">
, or<input type="image">
elements. method
-
The HTTP method to submit the form with. The only allowed methods/values are (case insensitive):
post
: ThePOST
method; form data sent as the request body.get
(default): TheGET
; form data appended to theaction
URL with a?
separator. Use this method when the form has no side effects.dialog
: When the form is inside a<dialog>
, closes the dialog and causes asubmit
event to be fired on submission, without submitting data or clearing the form.
This value is overridden by
formmethod
attributes on<button>
,<input type="submit">
, or<input type="image">
elements. novalidate
-
This Boolean attribute indicates that the form shouldn't be validated when submitted. If this attribute is not set (and therefore the form is validated), it can be overridden by a
formnovalidate
attribute on a<button>
,<input type="submit">
, or<input type="image">
element belonging to the form. target
-
Indicates where to display the response after submitting the form. It is a name/keyword for a browsing context (for example, tab, window, or iframe). The following keywords have special meanings:
_self
(default): Load into the same browsing context as the current one._blank
: Load into a new unnamed browsing context. This provides the same behavior as settingrel="noopener"
which does not setwindow.opener
._parent
: Load into the parent browsing context of the current one. If no parent, behaves the same as_self
._top
: Load into the top-level browsing context (i.e., the browsing context that is an ancestor of the current one and has no parent). If no parent, behaves the same as_self
._unfencedTop
: Load the response from a form inside an embedded fenced frame into the top-level frame (i.e., traversing beyond the root of the fenced frame, unlike other reserved destinations). Only available inside fenced frames.
This value can be overridden by a
formtarget
attribute on a<button>
,<input type="submit">
, or<input type="image">
element.
