In GoLive, you typically build cascading stylesheets with the following workflow:
Use the CSS Editor to add CSS styles to a web page, link to an external stylesheet or create a new external stylesheet. You can also import CSS styles from a different web page or from an external stylesheet, or create a new external stylesheet from one of the stylesheet samples in the New dialog box.

Use the CSS Editor to define the properties of each CSS style. Properties that you can define include font sets, text size, border attributes, list attributes, background attributes, and absolute position coordinates.
If you’re using an external stylesheet, you can link to it from an individual web page using the CSS menu on the application window or using the CSS Editor. Or, you can use the CSS panel and the site window to link multiple web pages to it.
Select a page in the site window and then
view the In & Out Links panel and the CSS panel, which lists
the external stylesheets, to determine where stylesheets are used
in the site. You can also use these features to associate style
sheets with new pages. For more information, see Using the In & Out Links panel to view links.Apply class or ID styles to text and other items. You must manually apply class styles to selections in your page with the CSS panel, and apply ID styles using the Outline Editor or the Source Code Editor tabs on the document window. Element and inline styles, in contrast, are automatically applied to HTML tags in your web page.
You can also apply class styles with the inline
CSS Style preview or Type > CSS menu options.You can continue to modify any style’s properties with the CSS Editor. All content that uses the style will automatically reflect the changes.
