As you edit HTML and JSP files, you can format existing text by
selecting the text in the Design page and modifying its attributes in the
Text tab of the Properties view or by using the Format menu.
You can also quickly add tagging for common HTML elements using the Insert menu.
In some cases, element types are not available when editing in the Source
page. In the Design page, Insert menu options add both
the element container and an empty element nested inside the container, such
as a list item inside a list container element.
