No, you can't do this with markdown. You need the power of HTML to use these enhanced alignment features.

In RAW HTML mode, you can still add Markdown manually, but you won't have the editor to do it for you.

I have a problem. If I use Editor and make changes in Raw HTML, I lose all editor codes.

The editor has issues switching between the two modes. I can't go back to Editor mode after I start in RAW mode. Is that what you mean?

I do commands in Raw HTML, like "< hr> or <div ...>"
If I go back to Editor and make a single command (eg Bold or Italic), I lose all the "< hr> "... insert in Raw HTML .

Yeah sorry, I don't switch. That's a bug in the editor I guess.

Alright! Thanks for answering my question :)
