Tooltips Pro – Add tooltips in Joomla!
Display text or an image to your users when they hover over an element without clicking it using tooltips.
When the user moves their pointer over the text or image for which you have defined a tooltip, a small “hover box” appears. This field can contain text or an image. If desired, the text can contain HTML formatting, including URLs.
Use Anywhere
You can create these tooltips almost anywhere on your site. Not only in articles, but everywhere you can enter text, like in modules and components.
Tooltips are fully customizable via settings and CSS.
