I have flagged two questions and would like to know if I did the right thing by flagging them
Can anyone provide some insight on these type of questions? I feel they need to be closed.
Meh, I've seen a lot worse.
The first question is a bit underspecified and poorly-written, which probably explains the downvotes.
The second one seems OK. To a certain extent, we love duplicates; unless they are clearly duplicating identical information, they help to broaden the depth of questions and answers, and improve the Google search experience.
Whatt may seem obvious to you may not seem so obvious to someone else, and unless you already know what a Media Query is, you might not know how to get there from a Google Search.
