Hello, good day to everyone.
I am new to programming and as a self-taught person it has become very difficult to move forward which is why I am asking for your help.
I use a parallax as the product title, I managed to show the name of the selected product from the shop. but I still cannot program so that the background image must be the same main image or alternative image of the product in question. Could someone help me with this problem?
I attach the code as I modified it.
