We have WPT tests that do this with ZWNJ, eg [text-encoding/shaping-no-join-001.html](https://github.com/web-platform-tests/wpt/blob/master/css/css-text/text-encoding/shaping-no-join-001.html) As the only examples so far demonstrate arabic glyph-shaping, we should also consider the case where you might want...

If additive behaviour was defined on a per-property basis it could apply even where lists of items aren't natural - for example: ```html .disabled { text-decoration: line-through !add; } a...

I agree with Brad's comments above - we already have these concepts in CSS, we shouldn't be trying to reinvent an (arbitrarily-shaped) wheel. Someone mentioned `border-image` above - I think...

In that case it's the same complexity as `:has()` - i.e., it's complex (see eg https://github.com/w3c/csswg-drafts/issues/3345). `:nth-children(2)` would be the same as `:has(> :nth-child(2)):not(:has(> :nth-child(3)))` - although I think it's...

> I don't think having two functions is needed—all that is needed is that the functions are aware of what property is calling them. I suspect having the function evaluation...

[CSS page](https://www.w3.org/TR/css-page-3/#page-properties) states: > page-margin boxes inherit from the page context. The page context inherits from the root element. I would absolutely expect this to apply to to custom properties...

Re. different things depending on resolution, could you nest @media inside @image to do this? That would open all sorts of doors, without inventing another microsyntax.

I don't think it's a spec change, just implementations catching up with the spec. We had implemented the cubic reduction algorithm for box-shadow. I've now just tried patching in the...

Ideally _someone_ (code for "_not me_" :smile:) should update https://drafts.csswg.org/css-backgrounds-3/spread-radius to add the new proposed algorithm(s) and - most importantly - the ability to resize the box. Clearly a lot...

Using the Unicode Script property as shorthand for a ranges is a really, really good idea. More intuitive, less error prone, less verbose, and it's a public list that's already...
