this site mostly only exists because of skeletonin (thanks skye!). it was basicaly how i discovered neocities and what inspired me to make a personal site. i also inspected it lots to discover how to do stuff lmao (so you can thank skye also for the background image, that took me hours to figure out).
sadgrl.online also helped me a lot, and i'm still taking lots of resources from it (like most of the background gifs).
another site i'm using to learn is w3schools. it has a lot of usefull resources for a lot of programming languages, including html, css, java and python! i would recomend to check them out, they have really straightforward tutorials.
