Use the Display Options setting to specify CSS styles for controlling the format of the table in which the message will be displayed
The Search Hint Web Part emits your settings here as values for an XML element named . The default XSLT template places these as value for the style attribute of the tag in which the search hint text is placed. You can, therefore, enter any type of standard CSS style properties and values accepted in table tags here.
The most common use of these settings is to establish the width and top margin of the table. For example:
width:80%;margin-top:10px |
