This is an example of the column headings and support information
for the HTML Support History grid. For each HTML element or attribute
listed, the table indicates if it is supported by any of the
listed HTML standards (2.0, 3.0, 3.2 or 4.0) or reviewed browsers
(Internet Explorer, Mosaic, Netscape or Opera.)
A version number is given such as "3.0A1" (representing
Version 3.0, Alpha 1.)
Non-Support:
Represented for both HTML Specifications and browsers by
a "--" symbol.
Formatting Schemes
Color coded differentiation is provided for readers with CSS-capable
browsers. This makes the information much more visually obvious to
a reader than plain font styles, but it should not be necessary in
order to read the information properly. The colors I mention below
are the default style sheet colors I have chosen for the site. If
you are using a downloaded version of the site, these colors are
customizable.
First Support:Style: Italics. CSS: Red
The element or attribute was first specified
or implemented by this standard or browser. For any given
element/attribute a single browser and a single HTML
standard can claim first support.
Support:Style: Bold. CSS: Yellow
The element or attribute is supported by this standard or browser, but
was not the first among those reviewed to do so.
No Support:Style: Plain. CSS: White
The element or attribute is not supported by
this standard or browser.
