Hi! I have made an assignment on marking up a letter (https://developer.mozilla.org/en-US/docs/Learn/HTML/Introduction_to_HTML/Marking_up_a_letter), and I would like to receive some feedback on it.

Thank you in advance!
Hi @Zeliboba and welcome to the community 
Great work on this exercise. There are only two small things that could be improved:
class="sender-column" should be on the <p> and not the <time>. When doing that the date will get right aligned.<sup> tags should only be around “3” and “4” so it reads “3 × 103” and “3 × 104”.Everything else is correct. 
Have a nice day,
Michael
