Logo not showing!

I'm trying to put my website's logo (logo.jpg) on top of the green banner but nothing is showing. www.beforeicroak.com Here is the CSS stylesheet code for the banner:

/* HEADER */

}

#header h1 {

}

#header h1 a {
color:#d4d4d4;
text-decoration:none;
}

#logo {
margin:0;
padding:0;
height:127px;
}

#logo h1 {

/* END HEADER */

since the <a> is an inline element, and you have no content in it, there is no width and height. You need to assign a width and height to it (the same width and height of your background image):

height: 127px;
width: 512px;
