It seems logical that a <button> with -moz-appearance:none and padding:0 should be laid out exactly the same as a <span> with display:inline-block (see attached test case).  But unless you also specify

    button::-moz-focus-inner { padding: 0; border: none }

you get extra inner padding on the <button>.  The extra rule is undesirable because it's using undocumented internal-UA-sheet magic and because it has the side effect of removing the button's focus ring entirely.

There should be *default* extra padding on a -moz-appearance:none <button> so that the focus ring does not *by default* collide with the text; however, all of that padding should be reflected in forms.css's specification of the padding: property of the <button> itself, so that it can all be removed without resorting to undocumented internal magic.

(This comes up when you're trying to make some <a>s look exactly like <button>s on the same page.)

Probably a duplicate, but in any case...

We should just use outline drawing here, imo, not a border.  Or something.

In particular, looks like a duplicate of bug 140562.

I almost said "we should do this with an outline" in the original description but then wasn't sure if that would have any other consequences.  (Particularly, *can* you put an outline on the inside of a box?)

If that's right, then yeah, duplicate of 140562.

Yes; in particular you could use a negative outline-offset.

Though we would just want to draw an outline around the stuff in the middle there, not try to guess the offset from the button outer edge.

This has been fixed by bug 140562's patches.
