Formatting Schemes
Differentiation of feature support consists of three levels: first support,
support (support exists, but the browser/standard was not the first
to support it), and no support at all. I have tried to make the difference
between these support levels clear and obvious - even to users with less
capable browsers, but some explanation is necessary. Simple font styles
are used to differentiate between first support (italic, bold) and support (bold),
while additional colors are attached for these settings via style sheets
for browsers that support this feature. Color coded differentiation is
much more visually obvious to a reader than plain font styles, but it
should not be necessary in order to read this 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.
NOTE: For any given feature a single browser and
single HTML standard can claim first support.
First Support:Style: Italics. CSS: Red
The feature was first specified or implemented by this standard or browser
Support:Style: Bold. CSS: Yellow
The feature is supported by this standard or browser, but was not
the first among those reviewed to do so.
No Support:Style: Plain. CSS: Gray
The feature is not supported by this standard or browser
