What HTML tags are allowed within comments?

Currently we allow the following HTML tags in comments. To learn what they do, take a look at the W3C's HTML elements reference.

These tags can be used alone and don't need an ending tag.

These require an ending tag, e.g., <i>italic text</i>

  • <a> Defines an anchor
  • <strong> Defines bold text
  • <blockquote> Defines a long quotation
  • <caption> Defines a table caption
  • <cite> Defines a citation
  • <em> Defines italic text
