(wrist watch)



Imagine building a set of Web pages that include timed assessments or "test me" activities (preferably granular and context related). Your users might appreciate having this clock appear in a consistent place on each page. It certainly appeals to the familiarity of the physical world.

This demo also illustrates the use of reusable document objects. Reusable objects can help with the chore of maintaining standards and conventions for Web pages. An object is essentially a document within a document. The "inner" document (in this case, the clock) is simply called in from a separately maintained DHTML file and positioned as needed. Since the markup for the object is contained in a single external file, it can be updated once and then every page that uses it will automatically follow the new standard or convention.

and the technique for making the clock a reusable object.
