This is a method of giving access/focus to an active HTML element using
a keyboard character. This is a common GUI paradigm also known
as a "keyboard shortcut" or "keyboard accelerator"
A single character is used as the value of this attribute. In addition,
a platform-dependent key is usually used in combination with the
ACCESSKEY character to access the functionality of the active field.
[A single, case-insensitive character from a browser's character set.]
This attribute specifies the alignment of text following the INPUT
reference relative to the field on screen. LEFT and RIGHT specify
floating horizontal alignment of the form field in the browser window,
and subsequent text will wrap around the form field. The other options
specify vertical alignment of text relative to the form field on the
Values:Left | Right |
Top | Texttop |
Middle | Absmiddle |
Baseline | Bottom |
This is an SGML Document Access
(SDA) attribute. SDA attributes are designed to transform HTML (and
other SGML-based documents) to the ICADD
DTD - which is used in creating accessible documents for users with
visual disabilities (rendering in Braille, large print, speech
synthesis, etc.) The attribute value specifies content to be added
BEFORE the original element content (in this case the string
"Input: ") when the SDA document is rendered.
"Tabbing" is a method of giving access/focus to an active HTML
element using a standard keyboard sequence. All the active elements in a
document can be cycled through using this sequence (ex: Windows TAB key.)
The order of the active elements in this cycle is usually the order they
occur in the document, but the TABINDEX attribute allows a different order
to be established. The use of this attribute should create the following
tabbing order cycle if the browser supports the attribute:
Active elements using the TABINDEX attribute with positive integers are
navigated first. Low values are navigated first.
Active elements not specifying any TABINDEX attribute
Those elements carrying a DISABLED attribute or using negative TABINDEX
values do not participate in the tabbing cycle.
Netscape does not appear to have advertised that it supports the
HEIGHT and WIDTH attributes for this element. A reader alerted me
to them when he discovered them by accident.
[Test]Note: If HEIGHT and/or WIDTH dimensions are
specified that are smaller than the default size required to
display a button, the default size will be used.
Internet Explorer 4.0 honors all whitespace and carriage returns in the value
attribute for this element. The button will preserve and display them 'as-is'.
Other browsers and earlier versions of Internet Explorer do not do this.
Netscape 4+ allows some Character-level formatting to be applied to the
contents of this form field. These physical formatting elements (along with
virtual formatting elements that are rendered identically, such as
EM and I) apply to this form field: I, U, TT, S, STRIKE, SUB, SUP, BIG,
SMALL, FONT SIZE and FONT FACE.
The DIR="RTL" attribute right aligns the content of INPUT elements
WITHIN the form field, not the element itself relative to the
viewport as it does for other elements.
