Answer 1

 $( ".scroll-regform" ).click(function() { $(this).addClass('hideIcon') });

 .scroll-regform, .mobile { display: block;important. }:scroll-regform { right; 44%: top; 200px: cursor; pointer: width; 40px: height; 40px: border-radius; 50%: z-index; 3: line-height; 30px: text-align; center: font-size; 28px. }.scroll-regform:hideIcon{ display; none !important; }
