Stylesheets, Combo boxes, Form Guides and mandatory errors
So, in a Form Guide, I have a drop down that is required, and I have a blank line at the beginning of said drop down set as default. Thus if the user does not choose anything from the combo box and tries to submit, it turns red. Just what I want.
However, once the combo box turns red, when I click on the drop down, the background on the list is now semi-transparent, which makes it a pain to read if it is over other text.
I've been looking through the documentation, trying to find how I can modify my stylesheet to turn the transparency off. But I can't seem to find any information on how to define that (or any behavior on elements when validation fails). Am I just missing this or looking in the wrong docs? Can someone tell me what I need to change in my CSS file or point me to the doc with the correct info in it?
