What is a Mouseover?
A mouseover, sometimes termed a rollover, is a bit of programming — typically JavaScript — that creates a different effect on a web page, when the mouse rolls over a certain object or part of the page (like a segment of the text). The simplest mouseover can do things like changing the color of the text if your mouse rolls over that text. Yet mouseovers no longer have to be simple things. Rolling the mouse over part of the page can produce exciting graphics or changes in existing graphics or text.
