Antiquated HTML Snippets and Artefacts

Lots of mud at the base of the wall. I think it's a good sign. It'll be a bad sign if this list does't grow.

I do bemoan the loss of the <?xml-stylesheet?> processing instruction and the JavaScript XSLTProcessor API.

I'd only add the Safari Pinned Tabs `meta` tag (https://developer.apple.com/library/archive/documentation/Ap...), which had you define a simple black and white SVG. This image would get used when a user pinned your tab in Safari, in color when active and black when inactive.

Ohh, conditional comments. We had so many IE holdouts on our site, I think only around 2021 I removed the last IE specific fallbacks, and I think some conditional comments were a thing until 2020.

I’m not sure when I removed a bunch of `msapplication-` fields, but probably after 2021 ;)

I guess I can remove `apple-touch-` and `application-name` stuff next…

Forever burnt into my mind is PNG alpha work-arounds in IE:

    filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='image.png');

GeoURLs seem like they would still be useful today.

Love the ruby tags on Chinese text!!
