I've been trying to override the green borders that are applied in my theme's stylesheet, which have been adding borders and padding to the +/- list images, the datepicker icon, and the recaptcha images (which is especially a problem, as it sometimes causes the captcha words to be obscured). I've switched to the non-icon style of datepicker for now, but haven't been able to fix the border issue. This is the code I added to my css:
body .gform_wrapper .gform_body .gform_fields .gfield .gfield_captcha_container .gfield_captcha {
border: none; }
body .gform_wrapper .gform_body .gform_fields .gfield .gfield_captcha_container {
border: none; }
body .gform_wrapper .gform_body .gform_fields .gfield .gfield_input_datepicker_icon {
border: none; }
body .gform_wrapper .gform_body .gform_fields .gfield .gfield_list .gfield_list_icons {
border: none; }
But this hasn't fixed the problem. This is the form. Thank you for any help!
