Character Entities
As with any syntactic language, HTML has certain characters that have special meaning. The
two most obvious characters are the < and > symbols, which surround all tags. These
characters cannot be typed in directly if the designer’s intent is to display these characters.
Thus, all characters that a Web browser can display are assigned numeric values. In addition,
many of these characters also are assigned names. The numeric values are entered into the
source Web page as &#nnn; where nnn is some 3 digit value. For example, the < symbol is
entered as ’<’. Name values are entered into the source Web page as &name; where
name is the name associated with this character. Again, using the < symbol, this would be
entered as ’<’. The browser fully supports the set of characters defined by the World Wide
Web Consortium, in conformance with the standard.
Colors
The browser supports 256 colors. Colors can be specified by name, RGB percentages, or RGB
raw numbers. The HTML and CSS specifications suggest 16 named colors.
The 4630 IP Telephone Web Browser recognizes these color names, which are:
Beyond these 16 well-known names, we recommend using RGB percentages or raw numbers
to specify colors.
Fonts
Font specifications are one of the most important styles you can apply to a Web browser.
Because of the 4630 IP Telephone’s screen size, the browser has only a single font available for
use. Font weights such as normal and bold are supported. Finer font values, such as lighter and
bolder are not supported. Normal and Italic font styles are also supported. Font sizes are also
supported, specified by either percentages or raw numbers. However, percentages below 50%
all appear as the same size.
Although we found some problems with font specifications, fonts behave reasonably well given
the screen’s size and resolution. The only major problem found is the inability to specify font
families.
