tags, and translated and un-translated live data elements. You might have to make changes to the options in this category as you progress through the book and begin to pick up on the functionality of these elements. To make a change, simply identify the element's highlight color that you want to change, choose a custom color from the color picker, and then enable the Show check box to highlight the specific element. Alternatively, you can decide not to highlight a specific element by disabling the Show check box next to the specific element name. The Invisible Elements Category Invisible elements are HTML components that, in most cases, don't have visual interfaces. Instead, invisible elements, like the named anchor you saw in Chapter 3, is represented by various yellow-shield icons. You can use the Invisible Elements category of the Preferences window, shown in Figure 5.14, to customize which, if any, invisible elements are displayed in Design view. Figure 5.14. Use the Invisible Elements category to customize which, if any, invisible elements are displayed. [View full size image]   A complete list of functionality exposed by the Invisible Elements category is given here: Show: Enable or disable the display of named anchors, scripts, comments, line breaks, client-side imagemaps, embedded styles, hidden form fields, form delimiter, anchor points for layers, anchor points for aligned elements, virtual server markup tags, non-visual server markup tags, and CSS display (none) invisible elements. When working in Design view, you'll be able to differentiate the invisible element by looking for the representative shield icon. Unfortunately, these icons cannot be changed. Show dynamic text as: As you will see in Part V, "Dynamic Web Page Development," Dreamweaver displays dynamic text directly in Design view using either brackets ({ }) or the text {Recordset.Field}. You can choose which to display using this drop-down menu. Occasionally, I'll choose the bracket option alone; if I'm working with an intricate design, it's more important to conserve space than it is to display the text {Recordset.Field}. Server-Side includes: Server-side includes are text files you can reference in an HTML file using the <!#include file="filename" > tag. The benefit to using server-side includes is that they let you "include" large amounts of text, HTML elements, and so on in any HTML file without taking up a lot of visual space in Code view. The downside to using server-side includes is that they can be used in excess, ultimately becoming unmanageable. Enable this check box to show the contents of the server-side include in the document. Disable this check box to display an invisible element icon instead. The Layers Category Layers, as you will learn in Chapter 11, "Layers in Dreamweaver," are HTML elements that can contain text, images, media, and so on. The benefit to using layers is that they are stackable and moveable in the design window, enabling pinpoint accurate designs. As shown in Figure 5.15, the Layers category in the Preferences window allows you to customize the look of the layer when it's inserted into the design window. Figure 5.15. Use the Layers category to customize the initial look of layers as they are inserted into your page.
