Hi,
You should modify the styles, to vary the width of elements. For example, creating the following styles:
.cp_cff_clean #fbuilder .resetbutton.column2{width:25% !important;}
.cp_cff_clean #fbuilder .calbutton.column2{width:74.9% !important;}
I’m sorry, but the plugin support does not includes implement custom templates. If you prefer, you can hire our custom coding services to implement a custom template to your form. You only should contact me through the support page:

Best regards.
