Figure 4-10. Strong and emphasized text are rendered
differently
If common sense tells us that the
<em>
tag should be used sparingly, the
<strong>
tag should appear in documents even more infrequently.
<em>
text is like shouting.
<strong>
text is nothing short of a scream. Like a
well-chosen epithet voiced by an otherwise taciturn person, restraint in
the use of
<strong>
makes its use that much more noticeable and effect-
ive.
4.4.10. The <var> Tag
The
<var>
tag, another computer-documentation trick, indicates a vari-
able name or a user-supplied value. The tag is often used in conjunction
with the
<code>
and
<pre>
tags for displaying particular elements of
computer-programming code samples and the like. Browsers typically
render
<var>
-tagged text in italics, as shown in
Figure 4-11
, which dis-
plays the following example:
The user should type
<pre>
cp <var>source-file</var> <var>dest-file</var>
</pre>
replacing the <var>source-file</var> with the name of
the source file, and <var>dest-file</var> with the name
of the destination file.
