Change header in child theme
I have made style.css and I want to modify the header. I made a picture to go on header and insert the code:
.header_main_bg { background:url(images/header_bg.jpg) no-repeat top center; clear:both; padding:25px 0; position:relative; }
But nothing changes. What is wrong? Do I really have to go into the core file? I don't want to do that. Any suggestion?
