Html in markdown tiles

I'd like to add elements in a markdown tile in html e.g. a menu bar that uses < style > < div > < nav > < img >
It seems it is currently not supported.

Hi @dvd-p
Arbitrary HTML elements are not supported - and likely won't be supported, among other for security reasons, since it's quite complicated to strip/parse HTML.

@flamber Would it be possible to add a markdown pseudo-element that allowed styles only?
Or allow with only a style attribute?

My own use case is that I'd like to have text boxes with smaller text.

@jkubecki You can use h6, which is smaller than normal paragraphs: ###### header 6
