Interesting. I'll let the Monks who are more experienced with web development comment overall but I noticed the print decode_base64("PHNj.... and decided to try to decode it. It is some JavaScript(?) that has been encoded. It seems to just be doing keyword color highlighting for some program code. I first used a webpage to decode it and then the following script.
use strict;
use warnings;
use MIME::Base64 qw(decode_base64);
print decode_base64("PHNjcmlwdD5mdW5jdGlvbiBjb2xvcihjb2RlKXt2YXIgcz1bX

I reformatted it slightly to try to make sense of it but I don't have the time or patience to take this any further. Good luck.
