I can't realize why bottom margin doesn't apply to the menu bar. I tried all types of paddings, margins and everything. I have no clue what to add or change so it can apply to it. I was trying to put position relative to #header and absolute to .menu and then all broke.  I dont know what I did wrong? 
My HTML:
<body>
<div id="wrapper">
<div id="header">
<div id="header_left"></div>
<div id="header_right">
  <div class="menu">Naslovna</div>
  <div class="menu">PVC stolarija</div>
  <div class="menu">ALU stolarija</div>
  <div class="menu">Ostali proizvodi</div>
  <div class="menu">Reference</div>
  <div class="menu">Kontakt</div>
  </div>
  </div>
  <div id="header_line"></div>
  <div id="content">
  <p> </p>
  <p> </p>
  </div>
  <div id="footer_line"></div>
  <div id="footer"></div>
  </div>
 </body>
 </html>
My CSS:
  @charset "utf-8";
