Coding links in CSS Options

[4111989]

Hi there-

I'm currently designing my first tumblr theme from scratch and it's almost done but I can't figure out how to change the CSS for links! I've tried a dozen different codes and nothing has changed it. There must be some simple code I can insert. Here's the current code if it helps:

CODE

<style type="text/css">
body {
background-color: none; background-image:url(http://i49.tinypic.com/2yytvrc.jpg) ;
color: #000; font-family:tahoma; font-size:10px
}


#posts, #content {
background-color:white ;
color: #000; width:600px; position:absolute; top:10px; text-align:justify; line-height:7px; border:10px dashed 1F2F41; font-size:10px
}

#posts {
background-color:white ;
color: #000; width:600px; position:absolute; top:10px; text-align:justify; line-height:7px; border:10px dashed 1F2F41;
}

#description, div{
background-color:white ;
color: #000; width:600px; text-align:center

}

{CustomCSS}
</style>

My tumblr is here: http://drugz.tumblr.com

TIA!
