Creating styles for an individual page:

• open (in Dreamweaver) Web document with text
• Window>Styles
• Style Sheet button
• Choose New
• Make Custom Style (class)
• Name the new style
• Select options
• Done and quit
• Highlight some text with cursor
• Select the new style in the style panel

The above steps only create styles that are determined by code in the head of the document you are using the styles in. If you want to create styles that control the text formatting on multiple pages you must create an external style sheet by doing the following:

Creating styles for multiple pages (external style sheets):

• Open a page of text in Dreamweaver (save it to your folder)
• Choose Window > Styles or click Styles in the Launcher.
• In the Styles palette, click Style Sheet.
• In the Edit Styles dialog box, click Link.
• Create a new external style sheet by entering a file name that doesn't exist yet.
  (External style sheets must end in the .css extension).
• Choose Link to specify the tag used to attach the external style sheet and then click OK.
• The external style sheet appears with the word (link) after the name on the list of styles in the Edit Styles dialog box.
• Double-click the style sheet name.
• A second Edit Styles dialog box appears.
• Click New to define styles in the external style sheet.
• Click Save when you have finished defining styles then Done.
• Link to this style sheet from any page you want to apply the styles to using the styles palette. (Click the Link button then Choose the file Dreamweaver just created in your web site folder.)
