In chapter 1 where the map is first applied, it would appear that some CSS entries are missing from the book text. I was able to fill in the missing css by searching through the completed project on Codeplex:
Code:
#theMap
{
position: relative;
width: 580px;
height: 450px;
border: solid 1px #bbd1ec;
}
#mapDiv
{
float: right;
width: 522px;
}
#dinnerDiv
{
float:left;
width: 235px;
padding: 10px 0px 0px 20px;
}
