Need Help With Customizing Customer Sign Up Page

[OiRGkCXXzs]

I was wondering if someone could help me with customizing the customer log in page? I have searched for the last day and a half trying to find out how to get rid of the gray borders that seem to represent the div tags in the form fields. I searched everywhere for a way to modify this in css but have had no success. The element information from my Web Developer Tool Bar points to form fields labeled "#loginForm" and "#createAccountForm". How can hide these borders or change the color to match the background? I have attached a picture. If there is a post already here that can help me out, please direct me to it. Thank you.

In your stylesheet.css look for
FIELDSET {
border: 1px solid #CCCCCC;
margin: 0.5em 0;
padding: 0.5em;
}

Thank you keneso.

I added that style back to the style sheet and modified it because the original code somehow vanished. All is good now. Again I thank you.
