this is not possible unfortunately. Header backgrounds are made with css which is incompatible with responsive. CSS backgrounds are @media only screen attributes are just technically incompatible.
Only plain images can be responsive but plain image won't work as background just like you want. So basically, it is impossible at all to make those backgrounds responsive.

#Subheader { padding: 16% 0 80px;background-size:contain; }
