The CSS Working Group just discussed `Define Media Groups: continuous vs paged, etc.`, and agreed to the following:

* `RESOLVED: Add definitions for paged and continuous media to MQ4`

<details><summary>The full IRC log of that discussion</summary>
&lt;heycam> Topic: Define Media Groups: continuous vs paged, etc.<br>
&lt;heycam> github: https://github.com/w3c/csswg-drafts/issues/5019<br>
&lt;heycam> florian: a while back we discussed that media groups weren't define anywhere but CSS 2, and defined vaguely<br>
&lt;heycam> ... concluded they're not actually used anywhere, except a few props saying they apply to all media groups<br>
&lt;heycam> ... fantasai found one other place where we use this, which is wrt fixed positioning, where we have a different behavior between paged and continuous behavior<br>
&lt;heycam> ... I think it does make sense to have a normative definition of this, MQs is probably a place for this.<br>
&lt;heycam> ... I propose we inline the definition where block-<br>
&lt;heycam> overflow is<br>
&lt;heycam> ... I would be inclined to say that for things that are fully scrolling without pages are continuous, and everything else as paged<br>
&lt;heycam> dbaron: I'd be inclined to say that the advertisement in the airport case [which minuter missed] is not paged<br>
&lt;heycam> florian: I agree it's a bit weird<br>
&lt;heycam> ... in practice it doens't matter much.  it's just going to be used for fixed pos, in a scrolling media it's going to be fixed, and in paged it will be replicated on pages<br>
&lt;heycam> ... so with neither paging not scrolling, it doesn't really matter<br>
&lt;heycam> stantonm: our default mode is paginated, but there's an option to switch to scrolling.  so I think this makes sense<br>
&lt;heycam> Rossen_: hearing mostly support<br>
&lt;heycam> dbaron: the thing I'm thinking about is that in the future, things that have neither pagination nor scrolling seem more similar to continuous than paginated<br>
&lt;heycam> ... if we're going to add any future distinctions on this<br>
&lt;heycam> florian: my intuition goes the other way.  but I don't think it makes a normative difference right now<br>
&lt;heycam> dbaron: don't feel strongly<br>
&lt;heycam> fantasai: defaulting to continuous sounds better<br>
&lt;heycam> ... the one that makes me concerned is things that are both continuous and paged<br>
&lt;heycam> florian: if you have pages, and fixed pos, I would expect the thing to be on each pages<br>
&lt;dbaron> s/sounds better/sounds better since people are mostly designing for continuous/<br>
&lt;heycam> ... the fact that some pages might be longer and have scrollbars doesn't invalidate that<br>
&lt;heycam> Rossen_: you'll add both continuous and paged media definitions to overflow?<br>
&lt;heycam> florian: this is just terminology.  I will tie this into the definition over overflow-block<br>
&lt;heycam> Rossen_: in MQ4?<br>
&lt;heycam> fantasai: given we're importing up from CSS 2 ...<br>
&lt;heycam> florian: we're importing words that didn't have a precise definition<br>
&lt;heycam> fantasai: MQ4 makes sense<br>
&lt;heycam> Rossen_: this will restart CR?<br>
&lt;heycam> florian: we need to do a republication soon folding in a few issues<br>
&lt;heycam> ... not going for republication just yet, but will in a few weeks<br>
&lt;heycam> RESOLVED: Add definitions for paged and continuous media to MQ4<br>
