Yesterday’s post was getting a bit long, so for those who weren’t doing web design in the late 90s/early 2000s here’s some background.

The constraints of 1999

The late 90s were a time of rapid change in the world wide web, the first big browser war was brewing. Netscape Navigator browser got bloated with the Communicator product they were pushing and Microsoft’s bundling of Internet Explorer with Windows rapidly pushed Netscape out of the market. Both implemented parts of HTML4 and CSS 1 and 2 in differently buggy ways, and they both had different ways of using JavaScript to animate elements on the page. Back then we called it Dynamic HTML!

The main constraints I’m following are:

CSS

CSS! Yes that’s right, we had CSS in 1999! CSS 1 support was reasonable, text and element alignment, text and background colour, and font face were reliable. Padding and margin worked on some elements. CSS2 support which included floats and positioning were not really ready.

Most existing sites still used <font> tags, but CSS was starting to be accepted. CSS let you alter text formatting on links (removing the underline was controversial to say the least) and IE4 introduced the :hover selector on a tags, allowing for mouse-over colour changes. Yes, bold-on-hover was a real thing we did!

Page layout

Layout choices are very limited. There’s no way to break an element out of the document flow (no floats, no CSS positioning), and there are only two ways to have multiple regions on a page.

First we have frames. Frames let you divide the window in to multiple separate named documents, so you could have a left frame 200px wide called ‘menu’ containing the site menu, and the rest of the document as a frame called ‘main’. <a target="main"> in the menu would cause the link to open in the main frame. This still exists as the <iframe> element, but frames are long deprecated. I won’t use frames in the main series, perhaps as an aside.

The other was the (mis)use of the <table> element. You’ll see this soon.

Fonts

Only fonts pre-installed on the user’s system could be used, no web fonts! In the early days this meant taking a guess and hoping. In the mid 90s Microsoft released their Core Fonts for the Web project, which was a bundle of fonts licensed for non-commercial use available for download. There was some traction getting them bundled on non-Windows systems, but it took a long time. Generally multiple fallbacks were provided.

Colour choices

Even though most people in 1999 had video cards that supported at least 24-bit “true colour” at 800x600 people using 16-bit “high colour” were still around. Due to how different systems mapped the colourspace it was common for colours that were distinct on one system to be the same on another.

Images

Even with a storage limit of 10MB this wasn’t the major restriction. Most of the world used dialup modems, with speeds of 56kb/s reasonably common. Even this extremely lightweight website would take around 10 seconds to download (though without custom fonts it’d probably be sub second), and the front page of English language Wikipedia would take close to two minutes.

This means decorative images had to be kept small to avoid stuttering loads - under 10kb each. SVGs were still a few years away, so we have GIF, JPEG and PNG.

Additionally browsers often only allowed a few requests in parallel (2-6 depending on your browser) so using multiple images would result in a site that slowly drew as each image downloaded in turn. Each request needed a whole new TCP connection, in New Zealand fetching from the US that would result in a minimum time of 250ms per image.

Animations

A memory surfaced during this project. In 1999 animations stopped when you scrolled the page. There often wasn’t enough video memory for off-screen rendering, so the whole content area was re-painted on every scroll action. If you dragged the scroll bar the document didn’t drag in real time, but if you pushed the down-arrow repeatedly animations would effectively stop as the timer was disabled during the re-render.

Character set

Unicode definitely exists, but it’s not in use. The ISO 8859-1 character set is generally available, though the Windows codepage 1252 is often actually used. Non-ASCII characters are rare outside of personal sites due to cross-platform and cross-language rendering problems. I’ll be sticking to ASCII characters.
