Capital Letters in Subtitel

Hi I've got a question about capital letters in subtitle. All words start in capital letters an i would like to chose if it has to be a capital leter or not. i already tried with css text-transform: lowercase!important; or text-transform: none!important; but it dosent work. Site url is: andreaflisch.ch and the subtitle with has to be changed is: "Farb-, Stil- Und Imageberatung" the word "Und" is written in lower case letters bau apperas always as "Und" with a capital letter. how can i change that? i know it's a tiny problem, but in german language the "Und" looks a bit weird with a captital letter. thanks in advance Greets Abdrea
