About Twitter Embeds:

> These meta tags (and some other, less frequently used ones) were used on Twitter when generating link embeds. However, the documentation and card validator are no longer accessible (previously at https://dev.twitter.com/cards/getting-started and https://cards-dev.twitter.com/validator respectively). X falls back to the widely respected Open Graph meta tags, making the Twitter-specific declarations largely useless. They should be removed in favour of Open Graph tags. Further, they should be removed because X is an awful site with poor moderation that is owned by a man who publicly performed a Nazi Sieg Heil salute and has directly contributed to the rise of fascism in the United States of America and globally, among other horrors.

Ok but I believe `twitter:card` has no OG equivalent and still works?

Reminds me of how awkward HTML doctypes used to be. Nowadays it's very simple, but in the past? You had to refer to the URL of the doctype declaration on every page

> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

This plus the X-UA-Compatible stuff mentioned in the article meant that for many people, the first few lines of code on a web page were something they probably copied from a tutorial or reference document every time, at least if they didn't have a CMS handy.

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

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

Hah, my thought as well, was a part of my standard page setup. And then using those transparent pngs to do rounded borders with 9 images nested within 9 divs!

Ha, fantastic line that one. Transparent pngs caused so much unnecessary trouble in IE6, it was very annoying, and limited our options as graphic designers.

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…

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.

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.

GeoURLs seem like they would still be useful today.
