The most compelling feature of web pages is the ability to click on something
(a link) and be "transported" to somewhere else.
For example, clicking on
Table of Contents
takes you to the Table of Contents for these notes.
Yet links are just another tag - here's what's behind
Table of Contents :
<a href="index.html">Table of Contents</a>
Looking at it piece by piece:
The tag is <a> - "a" is for "anchor"
because historically it referred to a place within the same document.
The attribute href specifies where
to go to when the user clicks on Table of Contents.
If you want to link to someone else's page, you must supply the whole
URL (Universal Resource Locator or simply the Location).
Here's an example:
<a href="http://www.aims.gov.au">Australian Institute of Marine Science</a>
