[css-sizing-3] Clarify auto value computation for width and height of inline elements

[gitspeaks]

According to CSS Box Sizing Module Level 3, Section 3.2:

auto - For width/height, specifies an automatic size (automatic block size / automatic inline size). See the relevant layout module for how to calculate this.

However:

1. The CSS Inline Layout Module Level 3 does not explicitly state that the width and height properties do not apply to non-replaced inline elements, as is explicitly specified in CSS2 Sections:

   • 10.3.1: "The width property does not apply."
   • 10.6.1: "The height property does not apply."

2. The specification also does not define the behavior of auto values for width and height of inline replaced elements, as described in CSS2 Sections 10.3.2 and 10.6.2

The CSS Inline Layout Module Level 3 does not explicitly state that the width and height properties do not apply to non-replaced inline elements

It's clearly stated in CSS Sizing: https://www.w3.org/TR/css-sizing-3/#preferred-size-properties

What does this mean?

Applies to: all elements except non-replaced inlines

I understand the part about inline elements, but why does this not apply to 'non-replaced' elements? How to read this ?

In any case, this aspect is not explicitly covered in the referenced module as written.

I don't understand your confusion. In the top comment you literally say "do not apply to non-replaced inline elements". CSS Sizing is just saying the same.

this aspect is not explicitly covered in the referenced module as written.

I'm not even sure what you expect it to say, since you quote the automatic size and then talk about the size properties.

It doesn't make sense for CSS Inline to define an automatic size because the size properties don't apply.

CSS Inline could repeat that the size properties don't apply, but it doesn't seem helpful since it's already on the propdef table in CSS Sizing.

I don't understand your confusion.

It seems like you're not fully considering what I wrote.

Here's the reference again:

"According to CSS Box Sizing Module Level 3, Section 3.2:

auto - For width/height, specifies an automatic size (automatic block size / automatic inline size). See the relevant layout module for how to calculate this."

I’m not saying CSS Sizing contradicts CSS2. What I’m pointing out is that the explanation isn't in the "CSS Inline Layout Module Level 3".

If the specification directs me to consult the "relevant layout module" for a calculation method, why isn’t it covered in that "relevant layout module"?

That’s not the issue. If the specification tells me where to look for something, I expect to find it there. If you think the location is incorrect, that’s fine—just provide a link to the proper place. However, if the spec points somewhere, it should be covered at that location.
