Re: [csswg-drafts] [css-grid] Decide on a name for `item-slack` (#10884)

The CSS Working Group just discussed ``[css-grid] Decide on a name for `item-slack` ``, and agreed to the following:

* `RESOLVED: use flow-tolerance for name and determine whether it will be useful for flexbox`

<details><summary>The full IRC log of that discussion</summary>
&lt;JoshT> fantasai: we had called this property item-slack and eventually went to item-tolerance. but we're not persuing item-* proposal now<br>
&lt;JoshT> ... but it's actually tolerance on the item anyway, so not a great name<br>
&lt;JoshT> ... people in thread seem happy with flow-tolerance<br>
&lt;oriol> q+<br>
&lt;JoshT> ... happy to go with that<br>
&lt;florian> q?<br>
&lt;florian> q+<br>
&lt;JoshT> ... it will apply to grid-lanes. we discussed for flex having a property that crams more things on the line, like shrinking when you're only going to overflow by something like 10px<br>
&lt;JoshT> ... we could separate it into two properties for flex and grid-lanes<br>
&lt;astearns> ack oriol<br>
&lt;JoshT> oriol: with what it applies to, I don't remember details, for how to apply to flex, TabAtkins and fantasai had different ideas<br>
&lt;JoshT> ... so for flex, maybe we need a different control for length and how to use the length<br>
&lt;JoshT> ... jen was saying it would work on normal grid layout, but I'm not sure.<br>
&lt;JoshT> ... if flex needs more control, I think it makes sense to split and have grid-lanes-tolerance<br>
&lt;JoshT> fantasai: we used the dense keyword to decide whether to cram, but then the proposal meant dense meant something else<br>
&lt;JoshT> astearns: but we're not certain?<br>
&lt;astearns> ack florian<br>
&lt;JoshT> fantasai: I think we would just need the length value and maybe negative value for the direction<br>
&lt;JoshT> florian: I think word tolerance is fine, but fit-tolerance is fine too<br>
&lt;JoshT> ... someone said could be confusing with object-fit<br>
&lt;JoshT> ... but I think still reasonable<br>
&lt;alisonmaher> q+<br>
&lt;astearns> ack alisonmaher<br>
&lt;JoshT> alisonmaher: I don't have strong opinion, but flow-tolerance could work as well<br>
&lt;djmarland> s/flow-tolerance/fill-tolerance/<br>
&lt;miriam> q+<br>
&lt;JoshT> astearns: I have slight preference for flow over fit and fill. those terms seem more overloaded<br>
&lt;oriol> q+<br>
&lt;JoshT> miriam: I also think fit and fill are distinct. here I don't know which to choose because the meanings aren't what we're talking about here?<br>
&lt;astearns> ack miriam<br>
&lt;astearns> ack oriol<br>
&lt;JoshT> oriol: I'm fine with flow-tolerance, but if it's not specific to grid-lanes, I would like a concrete proposal for how it would work into flex<br>
&lt;JoshT> ... we'd have problems if browsers support it for flex layer<br>
&lt;JoshT> s/layer/later/<br>
&lt;JoshT> astearns: any proposals for how to apply it to flex?<br>
&lt;JoshT> fantasai: we had talked but no independent issue for it<br>
&lt;JoshT> PROPOSED: use flow-tolerance for name and determine whether it will be useful for flexbox<br>
&lt;fantasai> Discussion on item-slack in Flexbox is at https://github.com/w3c/csswg-drafts/issues/11480<br>
&lt;JoshT> RESOLVED: use flow-tolerance for name and determine whether it will be useful for flexbox<br>
