In addition to the other comments people have made, relative URLs that start with a slash don't work the way you probably intend them to if you're browsing around with file:// paths. For example, a webpage located at /Users/example/Sites/example.com/index.html when loaded with file:// URLs will not find /Users/example/Sites/example.com/style.css if you use <link rel="stylesheet" href="/style.css">. (But you probably want to use "/style.css" rather than "./style.css" because then you don't have to keep track of arbitrary depths of ../ being added for files like /Users/example/Sites/example.com/foo/bar/baz/index.html.)
