These special characters, <, >, &, and " are the four standard HTML entities; and will not be displayed in an HTML document without special effort. In fact, using the first three in the source of a document will cause problems. HTML uses special codes, called entities, to display them. Entities must have a semi-colon ";" terminating them to be displayed properly.

Here is the code necessary to display them in your document:

<

Code: &lt;

>

Code: &gt;

&

Code: &amp;

"

Code: &quot;
Note: most browsers will display a normal quote character, (") identically to a entity quote character (").
