Create one or more web pages with the following effects using style sheets:

1. A hover effect for links
2. Turn off underlining for at least some text links
3. Apply some style sheet properties to some HTML element other than links to show how style sheets facilitate consistent formatting
4. Using 4 images, such as the images you created by slicing in assignment 6, display them as a single seamless image
5. Display two or more images so that they partially overlap. 
6. Then display these two images again, but change the Z-index value so that you alter which image appears in front
