Please Check Out My CSS, Does It Look Right ?

[mooapo]

Hello !

I was hoping some one could take a peek at my CSS and tell me if it looks right. I am new to Web Design and still learning.

body {
    background-attachment:scroll;
    background-color:#000;
    background-clip:border-box;
    background-image:url(img/bg-body.jpg);
    background-origin:padding-box;
    background-position:left top;
    background-repeat:repeat-xy;
    background-size:auto auto;        
    font-family:"Helvetica Neue", Helvetica, Arial, sans-serif; /* Serve Helvetica Neue, with Helvetica fallbacks to Arial */
    font-size:11px;
    font-weight:300; /* Better supported than 'lighter' attribute */
    line-height:18px;
    color:#444; /* Lighter on the eyes than #000 Black */
}

Also, is the image to large? What I am asking is, is the image right as well?

Thank you....

Hello mooapo,
I wonder if you really need all that stuff. Do you know what background-clip or origin is doing for you?

repeat-xy is invalid (see the links about validation in my signature line)

Maybe all of that could be tidied up a bit to look like this -

body {
	color: #444; 
	background: #000 url(img/bg-body.jpg);
	font: 300 11px/18px "Helvetica Neue", Helvetica, Arial, sans-serif;
}
