[css-fonts] Add font-size: math, math-depth and math-style #5536
Conversation
This imports the proposal from MathML Core to manage font scaling in math formulas using a new 'math-level' property. This mechanism involves a new 'math-style' property that describes compactness of formulas as well as a new 'math' keyword to specify relative font-size change using the a scale factor calculated from the 'math-level' changes. w3c#5389 w3c#5387

This probably needs improvements, feedback welcome ;-) Current test/implementation status is: Tests: css/css-fonts/math-script-level-and-math-style/ as well as indirect effect on MathML in mathml/ Chrome: Firefox: Safari: |

Hi @fred-wang ! I think we could use a bit of discussion about where exactly all this goes, but I do suspect it fits better into the MathML Core spec rather than the css-fonts-4 spec. The core processing of this all is fitted to the MathML layout model, and not particularly relevant generally to CSS, is why I'm thinking this. (Note: for the |
