Use Design-Time style sheets to show or hide a design applied by a CSS style sheet as you work in a Dreamweaver document.
In Dreamweaver CC and later, CSS Styles panel is replaced with CSS Designer. For more information, see CSS Designer.
Design-Time style sheets allow you to show or hide design applied by a CSS style sheet as you work in a Dreamweaver document. For example, you can use this option to include or exclude the effect of a Macintosh-only or a Windows-only style sheet as you design a page.
Design-Time style sheets only apply while you are working in the document; when the page is displayed in a browser window, only the styles that are actually attached to or embedded in the document appear in a browser.
You can also enable or disable styles for an entire page using the Style Rendering toolbar. To display the toolbar, select View > Toolbars > Style Rendering. The Toggle Displaying of CSS Styles button (the right-most button) works independently of the other media buttons on the toolbar.
To use a Design-time style sheet, follow these steps.
Right-click in the CSS Styles panel, and in the context menu select Design-time.
Select Format > CSS Styles > Design-time.
To display a CSS style sheet at design-time, click the Plus (+) button above Show Only At Design Time, then in the Select a Style Sheet dialog box, browse to the CSS style sheet you want to show.
To hide a CSS style sheet, click the Plus (+) button above Hide At Design-Time, then in the Select a Style Sheet dialog box, browse to the CSS style sheet you want to show.
To remove a style sheet from either list, click the style sheet you want to remove, then click the appropriate Minus (–) button.
The CSS Styles panel updates with the selected style sheet’s name along with an indicator, “hidden” or “design,” to reflect the style sheet’s status.
