html css drop-down-menu menuitem right-align

Right-align prebuilt navigation menu

I downloaded a menu from CSSMenuMaker.com and I love it, but I'd like to have the menu items aligned to the right without reversing their order and have the logo on the left. Right now I am using text to represent the logo, and right now I have it set to float:right. Any advice on how to right-align the menu items based on this code?

<li style="float: right;"> <a>  <div class='null'>
   THE LOGO </div>
   </a></li>
   </ul>
</div></div>

Solution

Here is what I did with the code you provided in the question:

Edited your code to include a separate .logo element inside #cssmenu that floats to left,
Floated the ul in the direct neighborhood of .logo to the right
Added micro-clearfix hack to the #cssmenu to avoid any collapsing often caused by CSS floats

See yourself.

@import url(http://fonts.googleapis.com/css?family=Montserrat:400,700);

.logo {
  padding: 17px;
  font-size: 12px;
  float: left;
}

.logo a {
  color: white;
  text-decoration: none;
  font-weight: 700;
}

.logo + ul {
  float: right;
}

#cssmenu:after {
  content: "";
  clear: both;
  display: table;
}

#cssmenu ul li,

#cssmenu #menu-button {
