Thank you for contacting us about our theme Sydney Pro. I am happy to help with your queries.

Can you share a link to your page here? I tried to find it, but couldn’t get it since I am only speaking English.

But I would like it to be the same for all blog entries.

Hello there,

Try adding this CSS code to Appearance > Customize > Additional CSS from dashboard.

    .single-post .site-header {
      background-color: rgba(0,0,0,4);
    }

    .single-post .sydney-hero-area {
      padding-top: 50px;
    }
