Use Invisibles Elements preferences to show or hide markers that represent invisible elements in the Document window. Showing invisible elements lets you select and view them, and change their properties in the Property inspector.

To change preferences, choose Edit > Preferences, click Invisible Elements, and then choose elements to make visible or invisible. A check mark next to the name of the element in the dialog box means the element is visible. View > Invisible Elements must be selected for the markers representing invisible elements to appear in the Document window.

Choose from the following options:

Anchors displays an icon that marks the location of named anchors (A NAME =) in the document.

Scripts displays an icon that marks the location of JavaScript or Visual Basic script code. Select the icon to edit the script in the Property inspector or to link to an external script file.

Client-side Image Maps displays an icon marking the location of client-side image maps in the document.

Embedded Styles displays an icon showing the location of styles embedded in the body of the document. Because styles are usually placed within the HEAD area of a document, these markers do not often appear in documents.

Anchor Points for Floating Elements displays an icon showing the location of HTML code for elements that accept the ALIGN attribute. These include images, tables, ActiveX objects, plugins, and applets. In some cases the code for the floating element may be separated from the visible object.

Line Breaks displays an icon that marks every line break BR.

Hidden Form Fields displays an icon that marks form fields where TYPE=HIDDEN.

Form Delimiter displays a border around a form.

Anchor Points for Layers displays an icon that marks the location of code defining a layer. The layer itself can be anywhere on the page. Selecting the icon selects the layer.

Backstage ibObjects displays an icon that marks the location of Backstage objects. The only way to modify these objects is in the HTML inspector or in another HTML editor.
