ADVANCED TOPIC: Assumes some knowledge of HTML and CSS.

Sometimes you want to show something only if there is data available to show. For example, let's say you're formatting some HTML and want to show the telephone number of a business. The following formats can do the trick.

<span style="[[ds:/Eats/restaurant/telephone:cssinline]]">and their 
phone number is [[ds:/Eats/restaurant/telephone]]</span>

Or, for block style elements, use this:

<div style="[[ds:/Eats/restaurant/telephone:cssblock]]"><b>Phone 
Number</b> [[ds:/Eats/restaurant/telephone]]</div>
