The BUTTON element allows for the creation of richer form control
widgets than the standard plain text used for BUTTON, RESET and
SUBMIT fields available via the INPUT element. The use of the
BUTTON element allows HTML formatting to be encapsulated
within these control widgets. The BUTTON element can contain most
any non interactive element such as character and block-level
formatting.
Rendering details for the BUTTON element have a few suggested
guidelines; The size can be suggested using style sheets, but the
actual dimensions are determined by following these rules:
Clipping of content should be avoided.
Button size may be increased to accommodate this rule.
Window edges should not clip buttons.
Button size may be reduced to accommodate this rule or the line
rendering of button content may be wrapped to allow a better fit.
NOTE: HTML 4.0 considers the use of
image maps in conjunction with images in the BUTTON element to be illegal.

Description:
"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.
Values: Positive or negative integers.
