The design of this website deserves some explanation, as it offers confusion to many users. No, it's not from the 1990s, and no, it's not broken. It's following strict design limitations for the purpose of truly universal display.
The focus on text is an important aspect of this site's design. Instead of constraining text between thick margins to create fixed fake page widths, the text simply wraps to the size of your browser, utilizing all of your screen for content. Without odd formatting, each page will wrap itself naturally for desktop and mobile viewing alike. Using simple concepts like "em spaces" for tabs and unicode characters for icons and pictographs, the site should load almost immediately over any connection. Currently, I'm cheating and using the Symbola font in WOFF2, WOFF, or TTF format, but as the newer Unicode standards proliferate into more popular fonts, the "serif" and "sans-serif" font-families which this site uses will eventually be enough to display a decent range of symbols. The idea is the same, though: use the basic standards to display all that is needed.
