At the beginning of SpryMenuBarHorizontal.css remove
@import url("../webfonts/Rockwell/stylesheet.css");
@import url("../webfonts/Rockwell/stylesheet.css");
@import url("../webfonts/Rockwell/stylesheet.css");
@import url("../webfonts/RockWell_Bold/stylesheet.css");
@import url("../webfonts/Rockwell/stylesheet.css");
A couple of other pointers
1. At this stage it is still mandatory to place a DOCTYPE declaration on line 1 of your document. Simply place the following
<!doctype html>
2. There are many instances of the same style sheet imported into the document. Remove all bar one of the following
@import url("http://aupair.host56.com/webfonts/Rockwell/stylesheet.css");
