Can I create a transaction in an offline electrum wallet that has never been online before and displays 0 as the balance, even though the balance isn't zero, and then broadcast that transaction to the network using an online HTML broadcasting tool?
I'm not sure about that, I haven't tried it myself.
What I've tried, though, is creating the transaction on an online watch-only wallet, transfer it then to an offline air-gaped wallet in a second device, sign it there, and then transfer the signed transaction back to the hot wallet to broadcast it.
