I am new and getting lots of downvotes. Can you see what I did wrong in these two examples? Help would be very much appreciated.
On your first answer, you said:
you have to explain deep or else they don't know what you want
Well... Yeah, that's what the question was, in a nutshell, saying. Answers are meant to answer the question, or in the case of Meta, at least further discussion on the subject at hand. This answer does neither.
On your second answer's first revision, you posted:
that is probably because the mobile web is different from the computer web, try again on a computer and refreshing the mobile web
Yep, the post author knew this. This was a bug report asking for the problem described to be fixed in the mobile web version of the site.
You then edited that second answer to say:
try to load it on a computer:)
Yes, the author knows that rendering the content on the desktop version will display it correctly, and is hoping that a developer would fix the described problem for the mobile view. This is just commentary. I recognize that this is a bug report and not really a "question," but this answer doesn't help anyone and isn't needed whatsoever.
Remember that the answer box is for answers to questions. From the help center on deleted answers:
Answers that do not fundamentally answer the question may be removed.
Downvoting lets users with access to the ability to vote to delete answers help delete answers that should be deleted, hence the downvotes on your answers.
