Online style guides For your home page and other formal Web documents, you'll need a style guide to help editors maintain consistency and correctness online. You'll have to add guidelines on standard headers and footers, electronic images, colors, use of tables and lists, file names and directory organization, and other Web-specific issues. Several organizations have put together style guides for their Web documents. One of the most comprehensive is that of the Yale Center for Advanced Instructional Media. Look at it and others to get ideas for making your own guide.
Informal documents have a place on the Web, too.
Just be sure to add disclaimers or other notices indicating how official they are or are not. When you find a typo on your home page, you can fix it immediately. With a book, you have to wait until the next printing. Ease of revision can also make an editor's job harder. Because Web pages are so easy to change, readers expect frequent updates.
