Left-floated, But Container Centered On Page?

[son]

I have a main div (.finish) inside a 900px container which containers left-floated div. The relevant css is:

{width:auto; height:auto; margin:0 auto;}.finish div {float:left;text-align:center;padding:10px; margin:15px; }.finish img {border:#625a29 1px solid; padding:1px;}.finish  h3 { font-size:90%;margin:0 0 10px 0;}

My problem is that I want to have all content center-aligned. The left-floating aligns all to the left (inside the div text and image is also aligned to center), but I need it to have several divs next to each other.Is there anyother way to display the content?Son
