Hi Claudia,
If you’re trying to hide it on just category taxonomy archive pages, you can try adding this CSS:
body.category header.page-header {
display: none;
}
If you’re trying to hide it on all taxonomy archive pages, you can try this:
body.archive header.page-header {
display: none;
}
If you’re trying to hide it on a specific category (example: Visit Rome), try this:
body.category-visit-rome header.page-header {
display: none;
}
