White Space under my FOOTER

I can’t get rid of this white space under my footer.. It doesnt display on all pages but some pages it will have an extra space under the footer.. Example page: https://supremesignals.com/step-2/

My footer bottom CSS Code:

#footer-bottom { background-color: #1f1f1f; background-color: rgba(0, 0, 0, 0.32); padding: 15 5px; }
	#footer-info {position: relative; width: 100%; text-align: left; color: #666; padding-bottom: 20; float: left; }
		#footer-info a { font-weight: 700; color: #666; }

Please help me make the footer 100% to fit to screen
