[SOLVED] Using version 3.4.3 vs. 3.3.3 Style.css??

I am working with the newer version 3.4.3 and went to edit the Style.css file and this is all I have to work with:
__________________________________________________ __________________________
/*
Theme Name: Atahualpa
Theme URI: http://wordpress.bytesforall.com/
Description: Version 3.4.3 - Build your own unique, professional and browser-safe WordPress Theme:

1-5 columns, fluid or fixed width, rotating header images and 2 dozen option pages. Support and

tutorials at our forum.
Version: 3.4.3
Author: BytesForAll
Author URI: http://forum.bytesforall.com/
Tags: white, one-column, two-columns, three-columns, four-columns, fixed-width, flexible-width,

custom-colors, custom-header, theme-options, left-sidebar, right-sidebar, threaded-comments,

sticky-post, translation-ready
*/

.aligncenter {
display: block;
margin-left: auto;
margin-right: auto;
}

.alignleft {
float: left;
}

.alignright {
float: right;
}

That's it? Where is the rest of it? Or, am I missing something in the upgrade from 3.3.3 for my other site?

Someone please enlighten me. There are adjustments I need to make on the new website I'm developing.

Thank you,

Craig
