Enlarging the view size on the same page

[banjundrama]

I couldn't find a really good site for this html css on-link thing. What I'm trying to do is to do the same thing as what is on the picture.

On the picture below, when I click the lil picture (where the red arrow is), the box where it says UNDEFINED pops up.

Question: How do I do that? And also, can I insert a video on the pop up box?

Thank you!

That's called a "lightbox". Typically done with javascript, it can be done with CSS but that's more than I have time to mess with. Google for that.
