REST Countries (Astro, React, Tailwind, SSG, ViewTransitions)

This is my first project using Astro and ViewTransition functions. I wanted to apply a slide animation when transitioning only from the index to the details screen, but I couldn't achieve it as I wanted without the details page changing all its content between others details pages (which was not what I intended).

Does anyone know of a comprehensive guide for implementing ViewTransitions? I also couldn't implement the transition: persist directive.

Thank you!
