Right fieldset border in DA created forms missing
I'm having trouble finding the css that controls the right fieldset border on forms created by DA (newest version). The DA form's right fieldset border doesn't exist or isn't visible on the page. I used to find page specific DA css on the page itself to make changes, but the world has moved on and the css isn't there anymore. I tried using Firebug, but didn't get anywhere with that. Can you please tell me where to look to find the css to make the changes I need to make? I attached a photo of the problem.
Also, I can't find the css to move the validation error bubbles from the left to the right side of text boxes. Thanks!
