HTML Arduino Help!

Hi I'm trying to create a HTML webpage using my Arduino Yun. I've seen some examples of people who have done this by printing the HTML code, something like this:

      US.println("HTTP/1.1 200 OK"); //send new page
      US.println("Content-Type: text/html");
      US.println();
      
      US.println("<HTML>");
      US.println("<HEAD>");
      US.println("<TITLE>Your Title Here</TITLE>");
      US.println("</HEAD>");
      US.print("<BODY BGCOLOR=\"FFFFFF\">");
      US.println("<CENTER><IMG SRC=\"clouds.jpg\" ALIGN=\"BOTTOM\"> </CENTER>");
      US.println("<HR>");
      US.println("<a href=\"http://somegreatsite.com\">Link Name</a>");
      US.println("<H1>This is a Header</H1>");
      US.println("<H2>This is a Medium Header</H2>");
      US.println("<HR>");
      US.println("</BODY>");
      US.println("</HTML>");

however, when I've done this I only achieve to print the HTML code in my browser, not to actually run it. Please help! What I'm I missing?
