You didn't supply a URL where you saw this effect so I'll guess it's a
"tool tip", typically done with the title attribute, but there are other
ways to show pop-up text, such as

You can use the title attribute on pretty much any element - links,
images, table cells, whole paragraphs, etc.

Just use pop-up text with caution. If the info is important, make sure
people who don't use a mouse can still get to it.
