Use the following Source Format preferences to control common HTML formatting preferences such as indent size, line length, and the case of element and attribute names. See Editing the source formatting profile for more information on additional HTML formatting controls.

Indent using lets you specify indents that use either spaces or tabs for those elements that have indentation enabled. By default, many elements will be indented if this option is turned on.

Indent Tables and Frames lets you indent these elements even if you have turned off the previous option.

Indent Size and Tab Size determine the size, in character spaces, of indents that use spaces and tabs, respectively.

Autowrap Lines wraps lines once they reach the column width specified.

Line Break Characters is useful for specifying the type of remote server (Windows, Macintosh, or X/Open® UNIX®) to which you'll post your files. Choosing the correct type of line break characters ensures that your source HTML appears correctly when viewed on the remote server.

Element and Attribute Names controls the capitalization of element and attribute names.

Always Use Preferred Element/Attribute Case converts all element and attribute names when importing an HTML document to the case you specify with the previous option. For example, if you always want to see element names in lowercase, specify lowercase element names and turn on this option. When you import a document that contains element names that are in uppercase, Dreamweaver converts them all to lowercase.
