[TYPO3-ttnews] different category HTML classes / uids

[Butch Harper]

Hi all,
i googled a lot but nothing functional found...
i want to style my different tt_news categories easily by adding the 
unique category id to my HTML class.

e.g.
<div class="tt_news_category1">My category 1</div>
<div class="tt_news_category2">My category 2</div>
<div class="tt_news_category3">My category 3</div>

could anyone tell me how to do that (really easy) thing? If i use the 
"title" then it's done via:

displayLatest{
	title_stdWrap.wrap = {register:newsCategoryUid}
	title_stdWrap.insertData=1
}

it's not possible to change "title" with "category" because nothing happens.
i tried a few other things like "dataWrap" or 
"DB:tt_news:{GPvar:tx_ttnews|tt_news}:category" but i don't get the 
point how to do that exactly.

thank you,
Butch
