Tooltips and PHP

[parayna]

Hello! Is it possible to implement tooltips into a PHP element? Basically, I want to put tooltips onto my register page (so instead of text next to the 'Username: ', a tooltip will pop up when they hover over an image of a '?' or the word itself. So that the explanation can be tucked away. I want this for all 'titles', so it looks a little less cluttered and so it looks better!)

I have tried doing it myself, Googling the information, and have tried various solutions from the internet but to no avail... could someone have an idea? Thank you ^_^

I will then probably use it for a lot more pages XD

(Oh, and I put tooltips in in preparation for Kyttias' Shop and Inventory mod, although I haven't yet put them in themselves. I only installed tooltips for now! -- I have to get all the shops and images planned and completed XD)
