Formating texts in registration/introduction header

I noticed that in the introduction of registration of a certain conference, they changed font sizes/colors and embeded urls to other webpages. Introduction is the first paragraph you are going to see in the registration page, just below the registration period/contact info line.

I wonder what kind of formatting language they used. Would it be markdown (then which version of markdown?) or plain html? I looked into the indico manual videos, but I could not find relevant information. “Markdown” was mentioned in several places, but I’m not sure if it applies to this case.

Secondly, I think it would be great to have a preview possibility of the registration page before making it public. Then I could test/modify the registration page and prevents errors before anyone supplies the registration information.


The introduction field uses markdown, specifically the python-markdown package, which implements John Gruebe’s syntax.

The registration introduction preview is a good feature to have, we will look into it.

Thanks for the feedback!

Since Markdown allows some limited HTML in addition to the Markdown syntax, most likely they just entered the HTML tags for this directly.

Tip: Inspect the content using your browser’s dev tools to see what markup was used to format it.
