TOPIC: additiona fields - length of display...

I have several custom fields on my form:

http://new.historicebenezer.org/event-r ... individual
(login/password: tech tech)

and the box length is not big enough for the text box fields and the email fields. Please indicate how I can increase the width of these fields.

Also, the font color needs to be changed. Please advise at to where I can edit that style.

Those are textarea fields. The width is set by columns. The textarea fields have two size settings... columns and rows. Columns = width, Rows = height. Adjust these and you'll be fine.

To modify CSS, make changes here:
/components/com_dtregister/assets/css/main.css

thanks for your help on the issue.
However, I did not make it clear that I want to change the font color of the text that is shown above the form. Where can I change that style.

You can change the font color in this CSS file:
/components/com_dtregister/assets/css/main.css

Look for "authorizenetformtable" and change the color for that class.
