WCSS Font and Text
mobile Internet site developers, the WCSS properties that everyone
has to deal with is probably the font and text properties, since
every kind of mobile Internet application needs to display text, and
very often the text has to be displayed in varied styles and sizes.
MP itself has provided a number of tags that can help change the font
style and size. For example, to display some text in bold type, you
can use the <b></b> tag pair; to display some text in
italics, you can use the <i></i> tag pair; to display
some text in a smaller font size, you can use the <small></small>
tag pair. (The <b>, <i>, <small> and a few more
tags are discussed in the "Font
Style in XHTML MP" section of our XHTML
MP tutorial. You may take a look if you are interested in them.)
using these XHTML MP tags will cause the presentation details to be
mixed up with the content and this is not desirable in many
situations. For example, let's say you make use of the <b> tag
to specify the bold font style to all level-1 headings on your mobile
Internet site (i.e. <h1><b>...</b></h1>).
Later if you have to remove the bold font style, you need to change
every "<h1><b>...</b></h1>" to
"<h1>...</h1>", which is very troublesome.
font properties defined in WAP CSS provide mobile Internet site
developers more control over the font name, font size and font style
of an element. In the past you cannot specify such details with WML,
but now you can do this with WAP CSS. However, note that the fonts
available in many mobile devices are quite limited, which means the
style you specified may not be supported in the actual mobile device.
For example, let's say you specify the Arial font to a paragraph of
text. If the Arial font cannot be found on a mobile phone, the mobile
phone browser will display the text using an alternative font.
