A web page is composed using a browser that displays an authoring web page containing an authoring tool embedded in the authoring web page. The authoring web page, as displayed in a browser window, includes a web page editing region that displays a web page under construction. The web page editing region further includes one or more user-specified instances of structured fields, each instance responsible for hosting content entered directly by the web page author through the browser window or identified by the web page authoring using the authoring tool. A composed web page is published, for example on the Internet. Thereafter, the composed web page can be rendered in a browser window of any client computer or device in a style consistent with the user-entered content in the web page editing region.
