Hide Image from featured content and Banner Image in Header

Hi, i have two questions 1)i have a problem with the featured content. I don´t want the image of the page to be displayed at the featured content excerpt. I already tried out the following custom css: /* Featured content image*/ #featured-content .featured-content-image { display: none; line-height: 0; } .single .featured-image { display: none; } .archive .featured-image { display: none; } .single #header-image { display: none; } .entry-container .wp-caption { display: none; } but nothing works out. I just want the featured posts/pages section without images. At the pages itself the image of the page should stay as it is. url: dogz.flohmi.at 2) at the place where the logo is, we want an image too. so it should be the logo AND an image (like a background banner). where can I do this? Thank you very much!
