I am very new to css so this maybe a simple answer. I have 2 scenarios and 1 works the other doesn\'t. I hope someone can help me out.
WORKS:
It looks like your CSS file is in the views/default/ folder, while the image is in the views/default/images/ folder.
views/default/
views/default/images/
Define image paths in your CSS relative to the CSS file, not the HTML file that displays everything:
background-image:url('images/home.jpg');
