Responsive Testimonial Slide with Tailwind CSS and JS

I finally finished this. I started this two years ago, but I gave up because there were several things that I didn't know how to do, even I didn't know how to search doc about that things that I didn't know. But, never is late to retry... Here, I improved my skills using Tailwind. My knowledge of positioning with relative and absolute positioning attributes also improved. There were some attributes I had never used before, but I had to learn about those, and that was the best part.
