Im using the McKinley theme (have child theme).
the header in the McKinley theme is roughly 150x1000px.
I wish my header to be about 50x1000px, its a .jpg file.
is there a way to insert it into the header using CSS, or do I edit the header.php, and put it in the childtheme folder?
Also, Im trying to tile the background with an image, but nothing shows up:
