You can have great fun with CSS. One trick is you can emphasize the top of your sitemap by making the text bigger than the pages below smaller & combined on a single line using CSS code like this




#sitemap ul li {
font-size:100%;
}
#sitemap ul li ul li{
font-size:90%;
}
#sitemap ul li ul li ul li{
font-size:80%;
list-style:none ;display:inline
}
#sitemap ul li ul li ul li ul li{
font-size:70%;
list-style:none ;display:inline
}
#sitemap ul li ul li ul li ul li ul li{
font-size:60%;
list-style:none ;display:inline
}




Just insert the above code in your 'Custom CSS' field in the page inspector. Notice how the 'top' level items are bigger than the lower level items and the lower level items are combined on a single line? Of course this is just one example but it should give you an idea of what's possible.
