Will this destroy my web site's layout?

In all test cases to date, Privly content has not affected page layout adversely. We can use sites in ways other than they were intended, like embedding a chat room in a Twitter feed, or putting a Wiki in an article's comment, but it does not change the layout or design of the host site. We hope the system will gain wider acceptance, and sites will be able to specify how injected content should be displayed. The core functionality of the Privly system can be used without a browser extension, if the host site runs our script.
