CSS Updates

CSS rules names

The current CSS class names are still using the HCC prefixes. We should move to the classic PF ones
.widg-c-drawer_header{}// should be something like.widg-pf-c-drawer_header{}// consult PF team
 

"Dangerous" rules

position: 'sticky'
 
Rules like sticky do have requirements on the parent component. We should test it with different containers and probably develop a wrapper component (default layout/page) that will have the necessary required rules which can then be used in the app.
