Use home network for learning browser-server communcation

I'm really new to html, css, javascript and all kind of web development. After I coded my first own website, I'd like to play a little with communcation between the browser and a server.

I'd like to be able to access a website hosted on my PC (using my PC as "Web" server) over my home network (my router) so that I can load and use it for example on my smartphone. There's no need for it being accessible over the internet, I only want to use it at home when being connected to my WiFi.

Is that possible and do you know any guide/tutorial for how to do this?
