Hi Very new to this and I am sure this is something simple. I've uploaded a resource, and in the theme editor using custom CSS I have added the following: .ipsHeader__primary { background-color: transparent; background-image: url('{resource="custom/Banner Image.JPG" app="core" location="front"}'); width: 100%; background-position: center bottom; background-size: cover; background-repeat: no-repeat; } However it does nothing - the file address is the address in the resource above the 'Use this tag in templates to insert this resource'. Any help would be welcome! Also - how do you change the images in grid view? Thanks
