Item styles in QuarkXPress 10 are like style sheets for items. An item style is a named package of formatting options for items. For example, you can define an item style named “Sidebar” that describes a box of a particular size and color with a particular frame, text inset, vertical alignment, and runaround — then assign that item style to a box by clicking the item style in a palette or pressing a custom keyboard command.
Using Item Styles you can easily create and apply styles to elements of your layouts such as boxes and pictures. Any time you create an item for which you have defined a style, you can apply the style in a single click.
