Just include the script at the beginning of the section, and invoke Tip('Tooltip text') to show and UnTip() to hide the tooltip, from the desired HTML eventhandlers. Example: My home page No container DIV required. By default, width and height of tooltips are automatically adapted to content. Is even capable of dynamically converting arbitrary HTML elements to tooltips by calling TagToTip('ID_of_HTML_element_to_be_converted') instead of Tip(), which means you can put important, search-engine-relevant stuff into tooltips. Appearance & behaviour of tooltips can be individually configured via commands passed to Tip() or TagToTip().
