How to make a looping carousel/slider (with arrows)?

Question

I'm currently coding a website for school, and I can't seem to make my slider/carousel work.

I'm trying to achieve this look :

carousel

The images must slide by 1 pic when a button is clicked, and it should loop (meaning the first pic to disappear should show up on the other side)

The fade effect is for later, don't mind it.

I've tried many thing, some using pure CSS, others with JS... I'm open to suggestions.

.slideshow {
  height: 240px;
  background-color: grey;
  overflow: hidden;
  position: relative;
}
.slide_content {
  display: flex;
  flex-direction: row;
  overflow: hidden;
  height: 100%;
}
.fluidimg {
  max-width: 100%;
}

This is a carousel that I also used for a project and it worked fine. Use the html, css and js in separate files as named.

To change the no. of images, see comments inside html
