Remove entire footer or hide top footer band
If you would like to remove the entire footer, first make sure that you have removed all content from Appearance / Theme Options / Footer and also set the Footer Widget to OFF. Save changes. If you are still seeing a copyright message please add this to your custom css under Appearance / Customize / Additional CSS
footer.footer { display: none; }
Sometimes you want to hide the widget band because you are not using widgets.
.footer { padding-top:0; }
or you may just want to hide the copyright bar.
.footer-btm-bar { display: none; }
Cheers!
