Coded in Astro
This is the official Astro tutorial, which does a walkaround over the main features of the framework, as well as providing some information about hosting the coding results with netlify.
There is nothing much else to add, but that the styles are custom and there is an extra animation trying to imitate the stars in the sky and some custom menu animations.
