Form Field Borders (Padding)

See attached. I want to put a white border around the grey form field text areas.

Here is part of the html. I only added padding to a few of the fields to see if it works; it doesn't.

Name*: <input type="text" size="20" name="cname" style="color: #000; background-color : #efefef; padding: 5px;"><br>
                                                Address*: <input type="text" size="20" name="addr" style="color: #000; background-color : #efefef; padding: 5px;"><br>
                                                City*: <input type="text" size="10" name="city" style="color: #000; background-color : #efefef; padding: 5px;">, Zip*: <input type="text" size="5" name="zip" style="color: #000; background-color : #efefef; padding: 5px;" value="<? print $_POST['zip']; ?>"><br>
                                                Billing Address if different from Service Address:<br>
                                                Billing Address: <input type="text" size="20" name="baddr" style="color: #000; background-color : #efefef;"><br>
                                                Billing City: <input type="text" size="10" name="bcity" style="color: #000; background-color : #efefef;">, Billing Zip: <input type="text" size="5" name="bzip" style="color: #000; background-color : #efefef;"><br>
                                                Telephone*: <input type="text" size="10" name="phone" style="color: #000; background-color : #efefef;"><br>
                                                E-Mail*: <input type="text" size="30" name="email" style="color: #000; background-color : #efefef;"><br><br>
                                                Credit Card*: <input type="text" size="20" name="ccno" style="color: #000; background-color : #efefef;">
                                                Expiration Date*:&nbsp;Month:&nbsp;<select name="expmo" style="color: #000; background-color : #efefef; width: 50px;">

I am trying to use padding, but it doesn't work.

How can I do this?
