In CSS Customization some little yellow triangles with an "!" mark have been appearing warning trouble, I guess. One of them says, about a background-color line: "Fallback background-color (hex or RGB) should preced rgba background-color."
Which my Hero theme obediently came with.... except that when a
the background is NOT transparent. When I take the first line off, it works perfectly (as it has always do before), but I get those annoying yellow warnings.
How can I fix this?
Thanks a lot in advance for your help.
