Centering a Logo in Fashionistas

Hi All,

I am working on my girlfriends fashion blog, and cannot seem to center the logo. I have read the other posts and have updated the CSS using the code attached below, but the logo is still not centered. How do I center the logo?

.site-branding {
	float: none;
    	text-align: center;
	}
