I downloaded the htm and css files for one or my forms and modified the code to a whole new design. This includes new radio buttons, how do I link the png files for the radio buttons using the custom css code block?
I'm not 100% sure what you're asking here, but maybe this will help: http://ryanfait.com/resources/custom-checkboxes-and-radio-buttons/ ? There's not a way to set new button CSS by default in FormAssembly. It will have to be in your custom code block.
