dialog-polyfill VS kill-sticky

> - Z-index has no effect in the top-layer. No need to compete for a higher z-index.

This is the kind of boring feature that can end up saving huge amounts of developer time. Z-indexing in CSS is kind of annoying and I've seen projects just detach dialogs from their normal position in the DOM entirely to get around stacking errors before.

Minor question:

> - There is only one `top-layer` but it can have many children. Last opened === current element on top.

Is this true? The spec says:

> The top layer is an ordered set of elements, rendered in the order they appear in the set. The last element in the set is rendered last, and thus appears on top.

I'm still playing around with `dialog` elements, so you may well be right, I'm just having trouble finding the actual spec rules about what happens when there are multiple dialogs and they're being simultaneously manipulated.

> - Not supported in Safari <= 15.3

Worth noting that there is a polyfill (https://github.com/GoogleChrome/dialog-polyfill), but that the polyfill comes with some fairly large limitations, specifically that they don't advise dialogs be used as children of elements with their own stacking context.

This is reasonable, but also... my first thought when I originally ran into `dialog` was "finally I can stop worrying about which of my elements create new stacking contexts!" -- so it does decrease the usefulness quite a bit.

Yeah, Safari is pretty often behind the other popular browsers. But, you can generally predict that by looking for any given feature on MDN and check the "Browser compatibility" section. Sometimes, there are polyfills available that sort of "force" a feature to work across every browser.

(Searching for "polyfill " will usually get you good results - in this case the first result appears to be a library maintained by the Chrome team: https://github.com/GoogleChrome/dialog-polyfill )

This does not make sense. Of course new functionality won't work on old browsers.

Kill Sticky bookmarklet[1]. Also works on mobile. Get in the habit of clicking it, you'll start using it a lot to recover that extra inch of vertical space that web devs love to take away from you for some bizarre reason.

Works in every browser (I use it in Safari on iOS and Firefox on desktop). These fucking stupid sticky elements are so common, I almost reflexively go hit this bookmarklet on every website now. It makes the web so much better.

In the meantime, NoScript[1] frequently avoids them entirely by just showing the page contents with no JS at all, and Kill Sticky[2] cleans up the ones that require JS to show you the content you actually want.

Or, a Firefox extension that adds a toolbar button: https://addons.mozilla.org/en-US/firefox/addon/kill-sticky/

kill-sticky just JavaScript so it will work on any browser

I found a fix!

Just add a little bit of code to a bookmark button, it works wonderfully.

Click the button and your scrollbar returns, the keyboard works again, _AND_ the page renders to a PDF beautifully.

You're welcome. :)
