Carousel using only HTML and CSS

I’ve been working on a site that uses a CMS that’s a bit limiting. I can add my own HTML and CSS to the site, but JavaScript is off-limits.I had some ideas of how I could make that work using CSS animations and the transform property, but that would leave me with a carousel that scrolled automatically and didn’t allow for user input which wasn’t really what I was looking for. After some thinking, I eneded up with a solution that uses absolute positioning and the :target pseudo-selector to change the z-index and opacity of our carousel items to cycle through them.
