Can I set background image and opacity in the same property?

Question

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?<

Answer 1

I had a similar issue and I just took the background image with photoshop and created a new .png with the opacity I needed. Problem solved without worrying about if my CSS worked accross all devices & browsers
