I am using Cassiopeia and Joomla 4. I want to add a slideshow.js and user.css file.
I have already added the CSS file and it seems to be picking it up fine. I added the slideshow.js, but doesn't pick up automatically? How can I include this in the head?
Also, when I update Joomla will these files get wiped like they did with Joomla 3.x?
Note: I realise the CSS file appeared because I called it user.css, but with the slideshow file I need to load that after every other JS file.
