Thanks very much for the replies. I am going to make this
message the solution as there is more than one and I can include
them in here.
For simplicity the ideas contained in Peter Grainge's
snippets page -
http://www.grainge.org/pages/snippets/snippets.htm
- under the heading
Tooltips are worth considering. Basically storing the pop-up
message as Alt text for images or in the <acronym title'"pop-up
message in here"> tag for text.
The RoboWizard solution of using Captivate was also a good
one but I didn't want to embed swf files into my html. Am I missing
anything here Rick? Please explain the idea further if I am.
Leon's solution is more complex and took me a while to work
around. As with complex solutions it does offer more flexibility in
that the pop-up message text that is to appear can be formatted and
images can be included. It makes use of a bit of JavaScript from
Walter Zorn -
http://www.walterzorn.com/tooltip/tooltip_e.htm
- for displaying tooltips. The tooltips can be kept in another
JavaScript file and called by Walter's script. An example of a
JavaScript function that can be called by Walter's script is:
function tooltip() {return "Type pop-up message in here and include
html code such as <B>bold</B>";}. Walter's page
provides plenty of examples.
I leave it up to the reader to pick their preferred solution.
