I didn’t say it is a server-side task but your server is serving the files, and your code alone – especially if I just copy it and run it in my browser – is still not telling us anything about whether images are involved or whatever else, and therefore it is more useful to see your live set-up. This is why I want a live example. The code you posted may be correct by itself but it doesn’t give any hints whether or not the file paths/locations are correct etc.
