interspersed with various html formatting tags. For example, a new paragraph is
begun with the tag
<p>
. The ending tag
</p>
is optional.
We describe a few of the formating tags-pairs that are used in html:
•
<font color=red> ... </font>
The text between the tags should be
red. This is the first tag that you have seen with an
argument
: In html, an
argument is given by a parameter name, the = sign, and the argument
value for that parameter. Java uses a
positional scheme
for giving argu-
ments: the first argument is associated with the first parameter, etc. Html
uses a
naming scheme: parameter
=
argument
. Therefore, the arguments
can appear in any order. Arguments are sometimes called
attributes
.
•
<font size=+1> ... </font>
The same font-tag pair as above, but
with a different argument, which increases the point size of the material
between the tags by 1.
•
<b> ... </b>
Put the text between the tags in boldface.
•
<i> ... </i>
Put the text between the tags in italics.
•
<u> ... </u>
Underline the text between the tags.
•
<br>
Practically the only tag without a corresponding closing tag. It
gives a line break, or new line character.
