Thank you for writing! There are many areas of Neopets where you can add HTML in order to give your pages a customized look. For instructions on basic HTML, please check out our guide, here: (http://www.neopets.com/help/html1.phtml).
We cannot provide any additional help with writing HTML and CSS, or customizing any guild, pet page, or user lookup. Our HTML filters are in place for a reason and you will need to make sure any code you create fits within our rules and filters. We can’t help you modify code to fit into your Neopets account.
Please remember to NEVER give out your account information -- someone claiming to be able to use HTML on your account is likely to be a scammer. Allowing someone else onto your account for any reason is considered cheating!
Also, please do not cover, hide or alter the stats, trophies or account information on your user lookup or pet description. All your stats and navigation links must be visible.
