Cant change H6 padding in custom css within Sydney theme

Hi guys
using this additional css within the Sydney pro theme

h6 {
    color: #F95F22; !important
    padding-bottom:20px; !important
    padding-top: 10px; !important

But it will not change the H6 padding - any ideas?

Temporary hosting for the site is

Please set this one to closed. Just realized I made a dumb error with colons before instead of after the important! declaration - sigh - sorry for wasting your time - still having issues though with the other job I logged and interaction with Pagebuilder.
