Shortcode output customization.

I am using bodly theme by site5themes.com Im using a button shortcode that i believe came with the theme. I also using ninja forms. That works good enough for me but the button is pretty ugly. It just doesn’t fit. So I tried using the css box to change how it look. I typed in the same attributes the shortcode has but it didnt come out quite right. So I tried giving the shortcode the attributes that the submit button had in order to use the shortcode button as the submit button. Every time I click on the shortcode’s button its link isnt anything but “#” although I removed the link atrribute and gave it the “input” attribute. Im deadly confused and getting very aggravated with wordpress. ( I F***s with wordpress though. ) I really need you guys’ help. Someone please help me ASAP!
