1. Create a parent ID for all the list items - Specify position: absolute and display: block
2. Style all the links in the parent ID to have equal height and display:block as well
3. Specify IDs for each icon - For each ID, specify the width of the icon and the left-position of it - Set the image as the background of the list item, but specify the location of the icon within the image
4. Specify a:hover properties for each ID - Copy the background property of the original IDs, just adjust the y coordinate
5. Set up the list in HTML - Use an unordered list with the parent ID and list items with the IDs created for each icon
