One of the most valuable forms of online resources is a library of examples that learners can actually manipulate and use.
About the example
The example shown here offers HTML ingredients that can be used in Web pages to create tables, headings, bullet lists, and so forth.
A learner can choose a particular ingredient from the table of contents and see both the formatted ingredient and the HTML code behind it.
The learner can then copy the HTML to an authoring program where embedded comments guide them in modifying the example to suit their purposes. Because such examples can be modified and used by learners, we call them active examples.
This example was built using Adobe Dreamweaver and JavaScript.
