XF 1.2 Can't seem to work this out

[oO5 Dynasty]

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.
