Replace Site Title with Image Problem…

I’ve searched, and found what looks like a workable edit to the child-theme css file. My logo is 432px wide x 200px high; however, when I put the code in, it’s cropping the logo. Can someone please review and let me know what I’m doing wrong? Thanks in advance.

css code snip:

/* Custom logo */
#site-title {
text-indent: -9999px;
width: 432px; /* width of the image file. */
height: 200px; /* height of the image file. */
margin:30px 0 0 0;
background: url(/wp-content/themes/twentyeleven/images/logo.png) #fff no-repeat;
font-size: 1px;
line-height: 1px;
text-decoration: none;
}

/*end custom logo */
