Using If Then Statements In Href Tag

Is it possible to use If Then statements in an a href tag? What I am trying to do is I am using a server side include page of navigation inside of a content management system. I have limitations on what I can manipulate and change. So just using style sheets won't do me the trick. I want to have a navigation link change a different color when you are on that section. I have the menu expanding also using if then statements. When a variable is passed somewhere else on the page as true, the menu expands. I figured I could use this in the same way to make the link change colors. I want to do something like:

<A href="#" <% If Variable_name then%> id="link <% end if %>>Link Here </a>

Is that possible? I know that i can do an If then statement and have 2 different links, one with the id and one without, but I wanted to see if I could simplify it at all. I'm not the best with ASP so there might even be better ways then that...I was just using from the little that I knew.
