Firstly, I am one word long.
Secondly, you will need the first three things.
You'll need a handful of guesses to figure out what I am.
But even if I tell you, I might be lying, mate!
Hint:
If you can't figure me out, you're a very unlucky person.
Hint 2:
Pay attention to one of the tags!
Hint 3:
Every clue and hint has a hidden element, except for this one
and the footer.
Hint 4:
Until the end, don't worry about the things three, for you won't need them.
Hint 5 (big hint):
This riddle apparently needs five (or eleven) handfuls of guesses. How many is that? Use math.
Deleted, this caused too much confusion as people thought this was a clue.
