CSS float wont work?

Question

Check this picture:

Now explanation: the RED circle is how i want the menu to be.. horizontal to the logo, but mine turns out like the green marked, the menu is "under".

And i think float function is the only way to do something like this(?) but it doesnt work, it wont float..

#top_menu {
height: 20px;
color: #333;
position: relative;
float: right;
}

#top_menu ul li {
        float: left;
        color:#333;
        padding-right:15px;
        font-family: Tahoma, Helvetica, sans-serif;
        font-size:11px;
    }

        #top_menu ul li a {
            text-decoration:none;
            color: #666;
            padding: 1px;
            padding-right: 8px;
        }

                #top_menu ul li a:hover {
                    color:#f2e9c9;
                }
#logo{
    margin-top: 15px;
    width: 200px;
    height: 30px;
    position: relative;
    right: 5px;
}

        <div id="logo"><a href="http://www.playcreatividad.com/es/index.php"&gt;&lt;img src="logot.png" alt="lolly"></a></div>
    <div id="top_menu">

Answer 1

Put the logo div after the top_menu div.

Answer 2

I can't see the screen shot you posted (blocked by the companies firewall) so I am not sure I know the exact problem. But if I understand correctly you want the Logo and the Menu on the same horizontal line. If that is the case you can:

1. Float the logo to the left OR

   #logo{
       margin-top: 15px;
       width: 200px;
       height: 30px;
       position: relative;
       right: 5px;
           float:left;
   }
   

2. Display the logo as inline-block

   #logo{
       margin-top: 15px;
       width: 200px;
       height: 30px;
       position: relative;
       right: 5px;
           display:inline-block;
   }
