logo in the centre

Hi,

Is it possible to align the logo in the centre of the template? not left or right aligned?
i can't find it in the file template.css

* Header block
*/
div.logo-text, h1.logo{margin-top; height:46px; width:310px; float:right}
h1.logo a{text-indent:-999em; display:block; height:188px; width:350px; background:transparent url('../images/logo.png') no-repeat 0 0}
div.logo-text h1 a{color:#fff; font-size:24px; text-decoration:none; text-shadow:1px 1px 1px #222}
div.logo-text h1 a span{margin-left:21px}
div.logo-text h1 a:hover{color:#ccc}
div.logo-text p{color:#999; margin:-10px 0 0 21px}

Many thanks
