Modal recommendations

Happy new year!

I’m working for a startup and we’ll use WordPress to host out corporate website. I would like to add a minimalist modal “take the tour” type slider to the site, it should allow me to add content and have small buttons so that the user can click through. I’ll add the content, text, images etc.

What is the easiest way to add this functionality, is there a particular plugin or can it be easily achieved using HTML within a WordPress page?

Any examples or help much appreciated.

Thanks!
