I would like multiple auto slideshows on one page with navigation options. It's for a portfolio showcase, I want 6 slideshows for 6 different projects. I have found this code https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_slideshow_auto. I like this, but when I try to change this code to have multiple slideshows, the second or third or … slideshow does not show any photo: it's empty.
I do not have a lot of experience in building websites. Hope someone can help me out.
