help with logo size

Hi, I’m having trouble with the size of the logo.
I found some post in the forums and I tried to add the code: #logo img, .stuck #logo img { max-height: 160px !important; } but is not working. it increases the logo but at the same time it puts it out of position. it brings the logo down and it touches the main image on the home page. and in the tab “Contact” it made the logo way too big.

Here is the link of the site http://sidest.apps-1and1.com
