In this video we look at an HTML page with two images. The img elements have mouse events (onmouseover and onmouseout) and the associated functions. These two events often work as a team, the first making some change and the second restoring some default value. We have the onmouseover function increase an image size and also change the font size of a nearby div element. The onmouseout event changes the sizes back. The functions associated with the second image include an invert style filter which has the effect of exchanging black and white.
