I remember transparency was handled with gifs back then, which had their own problems and limitations.

Alignment was either done via position: absolute or by using a table. The animated background here would be a bit more complicated with a table.

Risk of it breaking with some upgrade, or looking different for some people? As you said, very likely.

So server-side image generation was indeed the best option. And it was a popular and widely solved problem, even in the 90s: visit counters that showed the visits in the shape of an image were super popular.

Yeah, transparency on gifs is binary, so you always had a crunchy edge. Plenty of use cases, but nice looking text wasn't one of them.

And position: absolute did not behave the same way across IE, NN, FF, or safari.

For some reason I feel the sudden urge to have a drink.
