Logo positioning relative to menu

Hi everyone, I am trying to add a logo to

relative

to the menu and/or the header. So for example, if you look at my site, I want the red "CB" letters to the left of the menu. I should be able to position it as I want it but I need to know what CSS code I can use to make it relative to the menu. This is what I have at the header now, but I know it's not anything relevant really. <div style="float: center;"><img src="http://cinderellabridalandflowers.com/wp-content/uploads/2013/06/temp_logo150.gif"></div> My website: http://cinderellabridalandflowers.com Thanks a lot!
