Hello,

for design purpose i want to create a black area under the menu. Like this:

I put the following code into the custon css:

.page-header {
border-top: 35px solid #000000;

Works very good, but NOT on the woocommerce product-page:

I wonder is there a better way to achive this?

Thank you very much.
