if i want to add CSS where would i paste it?

Question

here is the page where i need to add CSS:

http://upload.wikimedia.org/wikipedia/commons/a/a5/Map_of_USA_with_state_names.svg

since there is no body and header, where exactly would i paste the css?

here is what it looks like currently and it does not work?

somestyle.css
<style>
#tt {
 position:absolute;
 display:block;
 background:url(images/tt_left.gif) top left no-repeat;
 }
 #tttop {
 display:block;
 height:5px;
 margin-left:5px;
 background:url(images/tt_top.gif) top right no-repeat;
 overflow:hidden;
 }
 #ttcont {
 display:block;
 padding:2px 12px 3px 7px;
 margin-left:5px;
 background:#666;
 color:#fff;
 }
#ttbot {
display:block;
height:5px;
margin-left:5px;
background:url(images/tt_bottom.gif) top right no-repeat;
overflow:hidden;
}
</style>
