12. Hyperlinks
Hyperlinks are at the heart of the world wide web,
allowing the user to quickly navigate from one web page
to another either in the same website or another website.

13. Hyperlinks
Hyperlinks can be absolute or relative.
An absolute hyperlink uses a complete URL
e.g. http://forrestercomputing.wikispaces.com

14. Hyperlinks
Hyperlinks can be absolute or relative.
A relative hyperlink will describe the path from the
current file location to the destination file location.
e.g. a web page called news.html located in the same folder
as the current web page could be accessed by the relative
address /news.html

15. Hyperlinks
The relative hyperlink from index.html to
topnews.html would be:
/news/topnews.html
The absolute link would be:
http://www.mysite.com/news/topnews.html

16. Hotspots
A hotspot on a web page which is activated when the
mouse is rolled over it (rather than clicked).
When the mouse hovers over a hotspot, something
happens e.g. image is zoomed.
In this example from
amazon.com the main product
image changes as the mouse
rolls over the different
thumbnail images

● Using history to navigate to a recently viewed page
● Clicking hyperlinks
● Clicking breadcrumbs to visit pages further up in the
