[css-contain] editorial: "element" should be "box" #4189
Description
https://drafts.csswg.org/css-contain-1/#containment-size
"... or if the element is a table, " (first sentence)
It would be clearer if you wrote "or if the box is a table box" given that the word "table" is linkified to https://drafts.csswg.org/css-display-3/#valdef-display-table. Ditto for other uses of "element is a ..." in this spec.
The term "containing element" occurs frequently in this spec. It appears there is no explicit definition of this term. As I understand it, what you mean is an element that has a principal box that satisfies the conditions in each section respectively. It's probably better to use the term "containing box" to refer to that box directly instead.
Quoting size containment as an example:
If the element does not generate a principal box (as is the case with display: contents or display: none), or if the element is a table, or if the element is an internal table element, or if the element is an internal ruby element, or if the element’s principal box is a non-atomic inline-level box, size containment has no effect. Otherwise, giving an element size containment has the following effects:
I think it would be clearer to say:
If an element does not generate a principal box (as is the case with
display: contentsordisplay: none), or if it's a table box, or an internal table box, or an internal ruby box, or a non-atomic inline-level box, then size containment has no effect. Otherwise, the principal box is a containing box for size containment and it has the following effects:
(and replace "containing element" with "containing box" in the text that follows)
