I'm not able to edit the question. Can anyone tell me what's the reason behind that? On hove that it will be show "Account is not allowed to suggest edits"
You have been temporarily banned from suggesting edits, as too many of your suggestions have been rejected.
You appear to be only adding JSFiddle links; that is not a good use of edit suggestions. In fact, it appears that is all you do with your edits.
Edit suggestions should address multiple problems in posts. JSFiddle links are perhaps better left in a comment.
The ban will automatically be lifted in a week or so; the goal of the ban was to make you stop and try and figure out why you were banned. That goal has been met; you stopped and asked for an explanation here.
