Bug 262789 – Sync and add missing 'UA' Stylesheet rules for 'fractions' in mathml.css

• Status: RESOLVED
• Resolution: FIXED
• Component: MathML

[Ahmad Saleem]

Hi Team,

I think we cannot add all rules, which are below as per web-spec:

/* Fractions */
mfrac {
  padding-inline-start: 1px;
  padding-inline-end: 1px;
}
mfrac > * {
  math-depth: auto-add;
  math-style: compact;
}
mfrac > :nth-child(2) {
  math-shift: compact;
}

.. We are lacking support for 'math-shift' and 'math-depth'. So I will add whatever I can in this bug.

mfrac {
  padding-inline-start: 1px;
  padding-inline-end: 1px;
}

mfrac > * {
  math-style: compact;
}

Just raising so I can fix it and progress (if any) WPT test cases.

Thanks!
