popup balloons

[Xah Lee]

there are two library for popup balloons:

• Erik Bosrup's overlib at: http://www.bosrup.com/web/overlib/

• Walter Zorn from: http://www.walterzorn.com/tooltip/tooltip_e.htm

however, their code is a bit dense to decipher.

i wanted to know, what is the basic mechanism to make this possible?

If you want just a basic prompt you do it like this:

<a href="info.html" title="Click for more">More...</a>

For HTML reach popups you creating a <DIV>, beautify it as much as you
want/can and place over elements by mouseover event.

The trick is to locate exact position and size of the element so popup
would appear on the right position. 95% of code volume in all popup
scripts is for the latter (popup position calculation).

Thanks a lot for this tip! It answered my question exactly.

Is it possible to give a slight more detail? I know CSS1 well. I
vaguely recall positioning and overlaying is a CSS2 feature?

Search this group's archives for 'tooltip'. CSS stuff is better asked
in a CSS forum such as comp.infosystems.www.authoring.stylesheets (ciwas).
