Funny how trying to do the slightest thing with technology (send some mathematics over email) immediately turns into a research project. Then if any of these images occurs inline, we need to figure out the baseline problem.Īnd so on. It seems Pandoc by default has a mode where it converts only “simple” expressions and throws a warning on math that cannot be converted to simple HTML (using "em" and "sup" tags and a Unicode alphabet for things like ∑), so we can use this as a trick to identify which math expressions need conversion to images. ) It turns out that simply using MathJax or KaTeX and pasting the resulting web page into an email doesn't work: Gmail doesn't support SVG images (security concerns?), so one needs to convert images to PNG, but then converting every $n$ or $x$ into a separate image feels like overkill (the email would become huge and slow to load), so it would be nice to only convert expressions that “really” need it. I'm just now trying to send some mathematics in an email (where most recipients will be reading it in Gmail), so I'm having to figure out what subset of HTML and CSS Gmail supports.
This wording expressly frames text/enriched as a stop-gap measure. It sounds to me like text/enriched was being proposed not so much as a replacement for HTML, but because HTML and related technologies were not yet mature enough. For those who will want to use HTML, Appendix B of this document contains a very simple C program that converts text/enriched to HTML 2.0 described in. > For these reasons, this document is promoting the use of text/enriched until other Internet standards come into more widespread use. The current RFC on HTML and Internet Drafts on SGML have many features which are not necessary for Internet mail, and are missing a few capabilities that text/enriched already has. Most MIME-aware Internet mail applications are already able to either properly format text/enriched mail or, at the very least, are able to strip out the formatting commands and display the readable text. On line 2 and 3, we define that mj-basic-component can be used inside mj-hero and mj-column.

However, there are two important reasons that this document further promotes the use of text/enriched in Internet mail over other such standards: Contain image mjml how to Contain image mjml manual Contain image mjml code Contain image mjml license Here is the important difference between the two: On line 4, we define that no other MJML component can be used inside it. In particular, HTML and SGML have come into widespread use on the Internet. There are other text formatting standards which meet some of these criteria.
