I have attempted to align the Gravity form in the home and get started page of http://www.gymrepair.com using the suggested gf_right_half and gf_left_half but it is not reflecting on the page. Please advice.
Thanks for writing in! This is a conflict with the latest Gravity form, our dev team is already looking into this. For now you can add this under Custom > CSS in the Customizer.
/*** fix gravity forms css ready class **/
body .gform_wrapper .top_label li.gfield.gf_left_half,
body .gform_wrapper .top_label li.gfield.gf_right_half {
float: none !important;
}
