It's called an anchor. It's part of HTML.
Cannot be done in iWeb directly.
Here's my solution :
Other solutions in this forum and on Google.
Keyword : anchor iweb
According to www.w3.org, an anchor is "a piece of text which marks the beginning and/or the end of a hypertext link. The text between the opening tag and the closing tag is either the start or destination (or both) of link."
An anchor which is the start uses - href="URL to the target file" - and can be created in iWeb using the Link inspector.
An anchor which is the destination can be created in iWeb using the Link inspector if its a "Back to the top of the page".
An anchor which is the destination uses - name="target-ID" - and is easily created using an editor but not so easy with iWeb since there is no facility for injecting code directly into the page.html doc.
Creating destination anchors is a bit of a pain which can lessened if you stay organized...
here is a different take using scriptaculous library:
there is no destination anchors, code injected and no post edit.
Thank you everyone! I didn't know what they were called (Anchors) and I don't know how to add HTML and some of the help offered was a bit too advanced for me to follow - but no doubt I'll find a tutorial showing step by step instructions on how to go about it!
Many Thanks Everyone!
