i would say PHP it, but Neocities doesnt allow PHP so rip. Honestly, if they allowed PHP, so many things would improve with Neocities as it would be a basically perfect web-host, rather than a decent one that lacks in some areas. I'm willing to pay $5 monthly (or maybe even $20) if Neocities allowed PHP thats for damn sure.
Reverted the "trio" background to the "TK" background
Suggestion: Add an option to change the background.
Otra sugerencia, es que ademas de poder cambiar el fondo, poder agregar otros estilos al fondo, como una con bajo brillo otro que literalmente vez la luz del cielo, otro con sombras... cosas así
