Moving the body to the left

[Zac.]

How do I move my entire blog to the left?

CSS:

body{
margin:0px;
padding:40px;
background:{color:Background};
font-family: 'Droid Sans', Helvetica, sans-serif;
font-size:12px;
line-height:18px;
color:{color:Text};
}

Do I need to add something?

[Zak]

float:left;

?

No CSS expert though, so don't quote me on that. :P
