Webpages use special markers, called "tags", to do effects. Tags are written using less-than < and greater-than > symbols, and most tags have a <start> and a </stop>.

Tags can make text bold or italic, and tags can add lines and underlines.

Because less-than and greather-than symbols mean tags, you have to use special patterns, called entities, to include these symbols in your web page.

Here are a list of some tags and entities you might want to use when writing web pages.

tag/entity what you write how it looks
paragraph <p>abc def</p>
<p>xyz uvw</p>

abc def

xyz uvw

italic abc <i>xyz</i> uvw abc xyz uvw
bold abc <b>xyz</b> uvw abc xyz uvw
underline abc <u>xyz</u> uvw abc xyz uvw
strike abc <s>xyz</s> uvw abc xyz uvw
superscript abc <sup>xyz</sup> uvw abc xyz uvw
subscript abc <sub>xyz</sub> uvw abc xyz uvw
line break abc <br> xyz abc
xyz
horizontal rule (line) abc <hr> xyz abc
xyz
less-than &lt; <
greater-than &gt; >
ampersand/and &amp; &

You can also combine them, you just have to remember to close them in the reverse order:

what you write how it looks
something <i>italic and <u>underlined</u> a</i> bit something italic and underlined a bit
this part <b><i><u>has it all</u></i></b> (just about) this part has it all (just about)
