Im trying to remove the header and logo block from all members profiles on my site. I would like for the members to use their own banner picture at the top of their pages. I cant seem to get the display none code to work at all.
.member_view #headerProxy{
display: none;

.member_view #logoBlock {
display: none;

did this on the default style and still nothing happened on the profile pages.
