I was wondering how I can make my blog a bit smaller and make it more taller.. ?

I was wondering i did this before, but how can u get an image this code, and to make it stay at the left side, so it wont repeat itself.

<style type="text/css">
div.blogheader, .caption {
font-family:Monotype Corsiva;
text-transform:none;
font-size:13pt;
background-color: #000000;
background-
color:#604878;
letter-spacing:2px;
text-align: CENTER;
width:424;}
</style>
