Having learned a few chunks of HTML and CSS, I put my first personal website online in 1998. It was a simple sort of personal website, with my modest bookmark collection, contact details (email and ICQ!) and a few graphical gadgets.
I utilized HTML layout tables, image sprites, frames and even an .htaccess password area (with nothing in there, but it was a proof of concept). And it was dark. Dark mode from day 1.
