However, Early Inmates, and users with "Self-committed" [paid] and Permanently Insane accounts can customize their embedded journals to the same extent as they can their journals on InsaneJournal. In almost all of the methods listed at http://www.insanejournal.com/developer/embedding.bml , the style ID number "101" is used. Style 101 contains hard-coded colors and does not contain comment links, which some users find limiting when attempting to embed their journal into their website.
If you are an Early Inmate, or have a Self-committed or Permanently Insane account, your embedded journal can have any look that you want, using custom styles (http://www.insanejournal.com/support/faqbrowse.bml?faqid=43) . When creating a style to use for embedding, be sure to check the box at the top of the page marked "Embedding?".
