Many people have asked how to do this, since this is practically a must in case of a long page. You must have a link that sends you to the top.
To add a link to a specific part of a page a chunck of code called an anchor is called. What it does is places an "anchor" on a particular part and a link is made to that anchor. So when the link is clicked it sends you to the anchor that you specified as the destination.
To make an anchor the following code is added:
<a name="destination"></a>
Whereby you should change the "destination" to something more memorable that is related to the thing you want linked to. This is the part that will not be displayed and is the anchor that is the destination.
The link to the anchor on another page is specified in the following way :
<a href="http://YOURPAGE.com/WANTEDPAGE#destination>THE TEST</a>
And the link to an anchor on the same page is done like this:
<a href="#destination>THE TEST</a>
Where your replace "destination" with the name of the anchor.
Click on this to go back to the top.
The code I used is this:
<a href="#top">Click on this to go back to the top.</a>
for the link and
<a name="top"></a>
for the location or the anchor that I put in the title field. Pretty handy, No?
