Change the background-changing example to change the color of the page to some other color.
In the same example add an id to the h1 header and add code to the
function to change the font to italics. The name of the font
properties is font. For more names of CSS properties in
JavaScript see this

For this problem you need to use a rollover of a picture with a "white square" picture to create an effect of appearing and disappearing picture.
Study the example of rollovers. Write a web page with two rollover pictures: one is initially invisible and suddenly "appears" when a mouse moves over it, and the other one is initially visible and suddenly "disappears" when the mouse moves over it. When the mouse moves away from the pictures, return them to the original state (the first one is visible, and the second one is invisible).
Use the pictures here:
It might be helpful to set the background of your page to a non-white color while getting this problem to work, and then reset it to white when you are done.
