It's the first day of #FOSDEM2026 and you shouldn't miss our 4 talks! Our colleagues @philn @koala @mariospr and @regocas will cover #WebRTC, #WebKitGTK, #GStreamer, Interop, #MathML, Web Platform and @servo

Edit: The problem seems to be that the setting isn't allowed for this Wordpress site. New order in then!

Does anybody have experience with Wordpress's "math block"? I can use LaTeX as input, but not MathML, even though it should be possible according to the site https://wordpress.org/documentation/article/math-block/.

LaTeX renders as math and MathML, but MathML doesn't get rendered.

#math #mathML #LaTeX #wordpress

@melissawm #MathML, of course.

Hatte vor einigen Wochen eine #MathML-Formel gebaut und davon ein Bild zum Einfügen in das Klausurblatt gespeichert. Heute beim Formulieren der Aufgaben gesehen, dass ein Teil der Formel (Zahl) nicht stimmig war.

Hätte peinlich werden können, wobei da vielleicht auch kaum jemand den gewählten Zusammenhang hinterfragen würde. ;)

Comment rendre les formules mathématiques accessibles sur le web ?

Dans cet article en anglais, Manuel Sánchez explore différentes pistes pour garantir leur bonne restitution par les lecteurs d'écran, notamment avec MathML :

SMathML: https://github.com/alpha-beta-eta/SMathML

> SMathML is a way to write mathematics on the web. More precisely, it is an embedded DSL in Racket for expressing MathML and HTML. By SMathML one can build high-level abstractions, such as transformations on XML.

@tonofcrates Thanks for this! My grasp of MathML and mathematical writing is better than HTML, so it may explain some of the confusion.

I tried to read into this a bit more. (This got a bit convoluted and ultimately I did the reading mostly for myself, so feel free to ignore this, if you have other more useful things to do!)

It is not really explained in that section why the list elements can't be children of <p> tags. (At least not in regards to the inline/block distinction.) It seems to me that the reason is that<ol> and <ul> are flow content and not phrasing content. Phrasing content is required inside <p> tags based on its content model.

On the other hand MathML math is phrasing content (but it is also flow content). This is why I would think that even having block-styled math should be allowed inside the <p> tags. Is there any other element that behaves in this way? That it can be either inline, inline-block or block element (by its 'nature' so to speak)?

Since this can't be separated from styling and CSS, I also looked into that.

With CSS you can have all sorts of combinations, but does it come down to inline/block distinction or the content model?

The CSS spec says that if a block box has another block box nested in it, the user agent(?) should only have block boxes inside the parent block box (https://drafts.csswg.org/css2/#anonymous-block-level). I don't see this as being a problem either, since <p> is a block box already. It seems that the user agent does the splitting into paragraphs by itself anyways.

Erfreulich, etwas über #MathML zu lesen, speziell zur Zugänglichkeit. Allerdings sehe ich die Nutzung von mtable für das Layout (!) mehrerer Formelzeilen kritisch. Das Element ist für Matrizen und ähnliche Ausdrücke zuständig. #HTMHell

🌘 conflores - 互通性與 MathML 核心
➤ 讓數學公式在所有瀏覽器上完美呈現：MathML 核心的互通性之旅
✤ https://conflor.es/blog/2025-11-27-interop-and-mathml/
本文探討了瀏覽器引擎在支援 MathML 核心（MathML Core）標準上的進展，特別是與 Sovereign Tech Fund 合作的 Interop 專案。文章詳細介紹了 MathML 的歷史演變、MathML 核心的誕生，以及為解決不同瀏覽器實作差異所做的技術性努力，包括 RTL 鏡射（字元級與字形級）和 math-shift/math-depth 等關鍵功能的實作細節。目標是讓數學公式在各種瀏覽器上都能呈現一致的視覺效果。
+ 很棒的文章！看到瀏覽器廠商們致力於讓 MathML 更加完善，真是令人振奮。特別是 RTL 鏡射的技術細節，讓我對字形級處理有了更深入的瞭解。
+ 我一直認為 MathML 的普及是網頁數學展示的關鍵。這篇深入介紹了背後的技術挑戰和解決方案，非常有啟發性。期待 W

RE: https://aslakr.folk.ntnu.no/2025/12/en-mathml-blokk/

Og det virker, både i RSS og ActivityPub.

Det hadde vært fint om Mastodon slapp igjennom MathML, men i det minste slipper den igjennom tekstfeltet (annotation) som inneholder LaTeX iht. FEP-dc88

En MathML-blokk

WordPress 6.9 har fått en byggestein/blokk for MathML:

Hvordan fungerer det i RSS og ActivityPub?

@MMagdowski Gibt es eine WOFF-Empfehlung, ohne alles durchzuprobieren?

Verwende im CSS für math { … } üblicherweise:
font-family: "Cambria Math", math;

Demos zu meinem #MathML-Artikel:
https://datenverdrahten.de/mathml/MathML_GL.html

Neil Soiffer und David Carlisle haben eine neue Website zum Testen von #OpenTypeMath-Schriftarten erstellt.

https://mathfonts.github.io/

Sie ist hauptsächlich auf die #MathML Darstellung ausgerichtet, enthält aber auch Tests, die PDF-Dateien (auf texlive.net) generieren, die die #LuaLaTeX Darstellung der bereitgestellten Ausdrücke mit allen Schriftarten zeigen.

Hier stehen etwa 30 Schriftarten zur Verfügung, was wohl nahezu allen frei verfügbaren #OpenType #Mathematik #Schriftarten entspricht.

Status of MathML after playing around for a bit.

• Pandoc has problems
• Support in SymPy seems broken. I also couldn't get a simple integral to render.

I'm kinda unhappy with this. Hope some MathML fan replies and explains me how I'm being an idiot (note: pandoc seems like it can be used ... )

@evilpie @firefoxnightly
This is excellent! #MathML included.

This looks like an excellent opportunity to tell #Mozilla (and hopefully the whole #WHATWG) to prioritize the #openWeb and #indieWeb over the corporate-controlled crapola they are pushing to transform the web into an OS they control: https://interop-rank.jakearchibald.com/

Of course my top votes went to #XSLT3 #JPEGXL #MathML and #SVG. https://wok.oblomov.eu/tecnologia/google-killing-open-web/ —pity none of the points are about #RSS or #SMIL though.

h/t to @dneto and @slightlyoff for bringing this into my timeline.

It would be so cool if the interoperable implementations of MathML-core (the de facto standard) would converge!
