If this is true to the original, I am surprised to see this was table-oriented layout and not a bitmap image with clickable x,y coordinates.
Table-oriented layouts was a thing back then too.
It was common to make tables and use them to assemble a bitmap, where each cell had zero border/margin/padding and an exact size, and contained a "slice" of the image. Web authoring tools (and Photoshop) even had explicit support for generating this sort of thing, as I recall. This was I guess simpler to automate than defining clickable regions of a single image, and it allowed for the individual pieces of the image to be requested in parallel on slow connections (adding another dimension of progressive loading).
Ah, nothing like trying to save the logo from such a website, then discovering the image you saved is partially cut-off and includes the navbar behind it instead having a transparent background.
Yeah, I remember this. Macromedia Fireworks had a slice tool that I used quite a bit. You'd basically make an image which was your website, and then do all the layout with zero border tables. But for me, this was what I was doing circa 2004 before CSS was dominant. Earlier software from the '96 era like Frontpage I think would use bitmaps whole cloth, but maybe I'm misremembering.
Looking at the code, it has definitely been modified from the original... there is now CSS as well as a google ad tracker... but visually it's probably almost exactly the same.
