Wow. This is kind of sad. So many memories.

The 90s are officially over.

If someone wants to feel a bit of nostalgia from the golden age of the Internet, here's the doc available from Internet Archive:

+1 for the usefulness of the page as a historical note.

Even if the page is deleted, some people will inevitably want a similar feature and might come up with ad-hoc polyfills, which would likely lack accessibility considerations. The page could serve as a guidance for such people.

That said, I don't think the polyfill in the original page was ideal either, because repeatedly changing visibility would be a noise to assistive technologies. Also, it might be nice to consider the prefers-reduced-motion media feature (though you should honor the flash thresholds of WCAG 2 either way).

Here is what I'm using for your information:

.blink {
    animation: 2s blink steps(2) infinite;
}

@media (prefers-reduced-motion) {
    .blink {
        animation: none;
    }
}

@keyframes blink {
    from {
        opacity: 1;
    }
    to {
        opacity: 0;
    }
}
