Thank you for your reply. What I comprehended from your post above is to do something like this ...
This setting will map the route
In the style.css, modify all the occurrences of the image files like this:
I made a total of 46 modification in the style.css which I actually did not want to because this is a third-party stylesheet and when they come with a new version, I will have to make the modifications again.
And, this attempt to solve the problem didn't succeed. I might have taken the wrong direction. If yes, could you pl. modify my configuration code and make it work?
Probably, the last alternative is to copy the image files in the build/public folder which means at the same level as the resulting stylesheet.css file.
