Image Maps were huge in the 90s. You’d have your landing page or header navigation as a giant image and just define shapes around the areas you wanted to be buttons. Saved you from having to chop the image up into tables. <input type=image> was similar but processed server side, clicking the image submits the form and reports the clicked X and y to the server. We used this at my first job a ton for maps. The MDN article actually doesn’t do this input type justice and misses their true use. HTTP 204 was huge too, and something I still use. Early way to send a message to the server without a page refresh before AJAX. If a request responds with a 204 the browser stays on the current page. Lots of star rating systems like on Amazon and early Netflix for instance used this. Click a star, link makes the request, 204 keeps you on the current page. Sometimes you’d add a little JS to pretty the interaction up. CSS active was usually good enough.
