General Template Question Beez 20 - Joomla! Forum - community, help and support

i'm getting ready design template , trying reverse engineer beez_20.

for life of me, can't figure out how change output of articles able manipulate <div> tags how choose. on featured articles page example, beez_20 displays full width article on top of 3 columns. i'd rather able use 960 grid system display articles in customized way.

one method thought of design index.php file standard container <divs> , within each article's html code, add in appropriate <div> grids there. however, i've noticed within administrator article editor, defaults putting <p> tags around content.

i'd rather able put

<div class="grid_6"><h2>header content</h2><p>paragraph content here</p><div class="clear"></div></div>

or have page display way (when viewing source). i've scoured forums/internet/tutorials/bought books, etc... , not 1 has had clear communication on this.

admittedly i'm not pro @ joomla , want dive in. i'm quite familiar moderate php , html/xhtml/xml. i'm wondering though, how template makers articles display how want them on each "page"

am battling core coding , not realizing it? there clear documentation somewhere of standard css should following in terms of class names, etc.?

thanks in advance.

edit: i've found on overriding core output , looking @ default.php file , cannot find item-column1, 2, etc being called/created.

i assume using category blog layout. colums output blog.php file , content of each afticle output blog-item.php.
