Adding link to slides - carousel

Question

I used this carousel from Codepen.
https://codepen.io/dangvanthanh/pen/AgHnB
I added links to each slide, but when I did, all the slides link to the link of the last slide. I even tried adding an onlick event onclick="window.location='https://codepen.io'" but without success.. Please help.
Fyi, Im a designer, not a front end developer, and Im just trying to put together a carousel for a website..

Answer 1

There you go:
Codepen
You were seeing this behaviour bacause the transition was using the slide opacity so the last link will always be in the front.
