I can see in CSS references how to set image transparency and how to set a background image. But how can I combine these two in order to set a transparent background image?<
if you need to set the gradient to background-image only:
background-image: url(IMAGE_URL); /* fallback for older browsers */ background-image: linear-gradient(to bottom, rgba(0,0,0,0.6) 0%,rgba(0,0,0,0.6) 100%), url(IMAGE_URL);
