In HTML, you represent all special formatting with tags. Tags
are delimited from the actual text by enclosing them in angle brackets:
<>
Tags to Mark Text
Most tags in HTML apply to a span of text. For example, to make text
bold, you can use the <b> tag. But you need an opening tag
(before the text) and then a closing tag (after the text). The closing
tag is just like the opening tag except that it has a forward slash after
the first angle bracket. For example, we could type this sentence in
HTML: One word in this line is <b>bold</b>, right?
This sentence would appear in a browser as: "One word in this line is
bold, right?"
Common tags that come in pairs include:
<b>something</b>
bold
<i>something</i>
italic
<u>something</u>
underlined
In most instances, however, logical tags are to be preferred:
<cite>something</cite>
citation
<em>something</em>
emphasis
<strong>something</strong>
strong emphasis
Six levels of headings are provided.
<h1>something</h1>
Heading 1 (for the most important level of headings)
<h2>
Heading 2 (for the next most important level of headings)
<h3>
Heading 1 (for the next most important level of headings)
etc.
Single Marks
These tags do not need a closing tag because they do not extend over more
than one character.
