Center align logo image but not menu icon

Hi,

I am setting up a theme and trying hard to center align my logo image. That worked, but my theme has a side menu and shows the menu icon and now the menu icon is centered as well, and i want that just to stay in the right top corner.

What i did was:

.site-header {
display: block;
margin-left: auto;
margin-right: auto;
margin-top: 0;
width: 19%;
position: absolute;
}

Hope somebody can put me out of my misery ??
