Notes
• Form content is defined using the
<button>
,
<input>
,
<select>
, and
<textarea>
tags, as well as other HTML formatting and structuring elements. However, they
may not contain other
form
elements.
• Special grouping elements, such as
fieldset
,
label
, and
legend
, are provided to
structure form fields, but more often tags like
<div>
and
<table>
are used to
improve form layout.
• HTML 2 and 3.2 support only the
action
,
enctype
, and
method
attributes for the
form
element.
<frame> (Window Region)
This element defines a nameable window region, known as a frame, that can independently
display its own content.
