I also tested it out. If it's going to be simple, remove this fancy styling; it makes it look complex and in my opinion, it doesn't add anything. It may just be me, but I like to get the least css if I'm going to do a serious procedure. Carefully decorates pages about bitcoin or cryptocurrencies remind me of frauds & shitty-tokenization.
Also, it seems that I've found a bug. You can't insert burning addresses[1], possibly due to less characters. It's probably reading the addresses improperly.
