Valid HTML tags in plugin output

This seems like a very obvious question, but I couldn’t quickly find an answer.

Based on the code here I understand that plugins can have some HTML in their output.

Is there a list of valid HTML tags that plugins can use?

In particular I would like to turn something link:

ERROR: Please check

into the same thing but with a clickable URL.

Many thanks!


You should be able to use whatever you want. Just don’t get over excited for <script> and on...= :wink:

Fantastic, many thanks
