RE: Reminder: Meeting today

That looks good. I recommend adding something to the Web Incubator CG at https://discourse.wicg.io in the CSS category.

Hi Tzviya,

Thanks for the information regarding the submissions.

Just wondering how much in advance… Regarding polyfills, did you mean something like https://w3c.github.io/mathonwebpages/examples/display/fraction1.html (this is work in progress) ?

Regards,

Dani

Hi All,

Apologies for not being attend. If you have proposals for the CSS WG, you should get them to the group well in advance of TPAC. They usually have a really packed schedule. The way CSS tends to work these days is with submissions of polyfills, not just ideas.

Tzviya

Hi, Everyone -

K-12 publishing in the Western Hemisphere will be eternally grateful if you guys can take up the elementary math use cases with the CSS group too. Long division and Stacked Equations especially.

I'll keep an eye out for any google doc you guys may start to make sure that these use cases get on the list.

Thanks for considering.

Best,

Minutes from 20 JULY 2017 Math On Web telcon
Minute taker: Arno.

Dani: would like to discuss with CSS WG about possibility to incorporate new CSS features that would suit out needs for mathematics.



At TPAC, we have the possibility to discuss with CSS WG what we would need to display mathematics without JS.



First we would need the scope of equations we want to support: fractions, matrix, big operators, supsub…?



Second, explain why CSS as it is is not enough to do represent those equations



Third, provide some hint/prototypes of what the solution could look like, perhaps with a Javascript implementation.



We need to do some planing to prepare for this, vacations are coming up for everyone.



Neil: I’m away in August.



Neil: For large operators, would that include stretchy parens?



Dani: yes, probably.



Neil: if we can suggest to the CSS WG some non-math use cases, that will help motivate them



Dani: which math would we want to do? For example, fractions?



Neil: Wouldn’t Peter have a list like that? Has he approached the CSS WG already with some proposals?



Dani: not that I’m aware of. Peter has had some unofficial conversations, perhaps.



Neil/John: square roots would be useful as well.



Neil: are fractions actually a problem?



Dani: sometimes the fraction bar need to be moved up or down, and it needs to be computed depending on the font size.



Arno: we would probably need to have the concept of “math axis” similar to the “baseline” that exist today



Dani: flex box allows vertical alignments, and that helps for fractions and big operators



Neil: sounds like flex box is solving the problem for big operators, then?



Dani: yes, partially. But you need to move the operator to align with the math axis.



John: sounds like we need to work on a list of those cases



Arno: we also need to think of integrals that require limits to be displayed offset from the symbol



John: is there that list somewhere?



Neil: I thought Peter had something, but that may have been a long time ago…



Arno: I’d suggest creating a Google Docs that we could all collaborate on, with the goal of having something ready in time for TPAC.



Dani: I will create the document and share it with the group so we can start collaborating on these ideas.
