Open the ss_dday.html and ss_layout.css files and enter your name and the date in the comment section of each file. Next, go to the ss_dday.html file and within the document head, create links to the ss_styles.css and ss_layout.css style sheet files. Study the content and structure of the document. Note that within the aside element is an image for the battle map with the id mapImage. Also note that there are six marker images enclosed within hypertext links with IDs ranging from marker1 to marker6. After each marker image are div elements of the mapInfo class with IDs ranging from info1 to info6. Part of your style sheet will include style rules to display these div elements in response to the mouse pointer hovering over each of the six marker images.
