[TYPO3-english] odd / even classes for every second record

[B.Wolf]

Hi there.

I'm using "insert records" to put often used boxes into the right column 
        of my site. To display them on the page I use the following code:

temp.boxenelemente = CONTENT
temp.boxenelemente {
     table = tt_content
     select {
       where = colPos = 2
       orderBy = sorting
     }
}

subparts.sidebar< temp.boxenelemente


Now every second box should have a different header-color, so I would 
like to wrap the first box-element in a div with the class 'odd' and the 
second in a div with the class 'even' - or something like that.
I have no clue how I could achieve this - any help is very welcome.

Thank you very much!
