Forum:Template request

I want to create a template based on Wikipedia:Template:Clarify, which includes mouseover text, but I can't figure out how to do that. Do we need an extension for that? I imagine it having the form {{clarify|this is the mouseover text explaining the problem}}. The Ultra-Mind (talk) 20:03, 26 October 2015 (UTC)

Can't say I'm thrilled with the idea of this template. Worried it will get spammed everywhere. Are others interested in having this? If so I can look into it. -- Fenyx4 21:03, 3 November 2015 (UTC)

It wouldn't be as useful is most of our articles, which can more than fit on a 1680x1050 screen, but it makes it a lot easier on our longer articles.

It's also not the only idea I've had for mouseover technology. I think I remember seeing a an article that was wall-to-wall animated gifs. That won't do epileptic patients any good or anyone else for that matter. If I found it again, I was going to suggest a mouseover might make it look better.
