[math-on-web] CG meeting minutes, 2017/08/31

Hi everyone,

Below are the minutes from the last CG meeting.

The next meeting will be on Sep14. We'll continue the discussion around CSS
polyfills.

Best,
Peter.


# [math on web CG] minutes 2017-08-31

* Dani, Neil, Peter, Volker
* Dani: new stretchy polyfill at
https://w3c.github.io/mathonwebpages/examples/display/stretchy1.html
  * splits up vertical vs horizontal
  * also probably need to separate serif vs sans-serif, so we should have a
custom attribute for that
  * Neil: not sure how serifs would show up in stretchy chars
    * Dani: horizontal lines can be thinner, vertical more bold
      * publishers will want distinction.
      *  ideally, match fonts in terms of thickness
* Peter: do you want to go thorough the polyfill?
  * Dani: prefer for people to take a closer look first
* Dani: I'm thinking we should create a collection of such polyfills
* Dani: it would be good to have something like a Unicode point for
"fraction line"
  * [discussion about exposing fraction lines to AT]
* Peter: in MathJax v3, stretchy will be done purely in CSS, no JS
required, just growing with the box
  * JS still necessary for choosing between the available sizes in a font
vs the truly stretchy constructoin
    * CSS element queries could help solve that.
  * Neil: can you share?
     * [screenshare]
     * Peter: ACTION yes, will have a public sample by next meeting
  * Peter: of course all approaches have drawbacks
* [discussion about CSS approaches to stretchy]
  * Peter: variable fonts could solve a lot of issues
    * and even more so things like https://spectral.prototypo.io/
* Peter: Dani can you post to the CSS tracker on vertical-align?
  * Dani: ACTION yes but want to publish polyfill first
* Dani: it would be good to get feedback for stretchy and fraction
construction
