Reusable content fragments are managed in a web site. The reusable content fragments are saved in a reusable content library in response to the fragments being created in a web page of the web site. When the web page is rendered for viewing, the reusable content fragment is rendered according to a first format when the web page is rendered for the author of the page. Correspondingly, the reusable content fragment is rendered according to a second format when the web page is rendered for another user. The reusable content fragment may be inserted into other web pages of the web site from the reusable content library.
