DIRECTORY Child CSS

Hi, I've installed Directory, the directory theme and a child theme
Could someone give me some basic css I could include in the child style.css file to make a basic but obvious change on my site. (LIKE changing the color of the the footer or something)

To date I have not been able to get any css modifiaction to show... am I missing something?

ps - this question box is white text while typing on a white background???? I also wanted to use the choices to select the installed theme but it diedn't show any?... so I've selected the directory plugin.??? But the stupid question form wont update.... ??????
