When you need it again, you can enable it. When you disable a CSS rule property, Dreamweaver wraps the CSS code as a comment. In the CSS Styles panel, you can use the Disable/Enable CSS Property button to disable or enable individual properties. When you disable a property, the red universal no sign (circle with a line thru it) appears next to it in the CSS Styles panel and Code Navigator. If you assign a new value to a dis- abled property, Dreamweaver automatically enables it.

In Live View, you can click the Inspect button on the Document toolbar to enable the feature. With CSS Inspect enabled, you can move the mouse over elements on your page to see the CSS box model attributes for any block level element. When an element is high- lighted in Live View, the corresponding HTML code is selected in Code or Split view. You can also view the CSS styles and properties for the selected element in the CSS Styles panel. CSS Inspect works best with the CSS Styles panel open in Current mode, and the Document window in Split Code/Live View and Live Code. If the workspace is not in this set up, the Info bar appears, asking you to switch to it. Inspecting CSS Code Inspect CSS Styles Open the Web page you want to view.

This reduces the size of your CSS code and makes it easier to read, debug, and maintain. When you apply a style to an element, any property that can be inherited is passed to any child, or nested, elements. For example, if you apply the font properties of Times New Roman and 14px to the <p> tag, any nested <em> element would also be Times New Roman at 14 px. If styles conflict, the style closes to the element is applied. You can use the Relevant CSS tab to help you determine which style is in control and make any adjustments that you want. Using the Relevant CSS Tab The Relevant CSS tab lets you track the CSS rules affecting the currently selected text ele- ment as well as modifying the rule's proper- ties. The Relevant tab is located in the Tag Inspector. Click the Window menu, and then click Tag Inspector. The Relevant CSS tab con- sists of two sections: ◆ The upper portion of the Relevant CSS tab shows the rules affecting the current selection and the tags that they affect. ◆ The lower portion of the Relevant CSS tab displays the properties of the currently selected element in an editable grid. The properties are arranged alphabetically, with the set properties sorted to the top of the tab. Set properties are displayed in blue; properties irrelevant to the selection are dis- played with a red strike through line. Hovering over a rule that is irrelevant displays a message explaining why the property is irrelevant. Typically, a property is irrelevant because it is overridden or not an inherited property. You can also use the lower panel of the Relevant CSS tab to modify the properties of a selection. The editable grid lets you change the values for any of the displayed properties. Any changes you make to a selection are applied immediately, letting you preview your work as you go. Using the Relevant CSS Tab From the Library of Wow! eBook .
