You can apply a set of steps from the History panel to any object in the Document window.
If you select multiple objects and then apply steps to them from the History panel, the objects are treated as a single selection and Dreamweaver attempts to apply the steps to that combined selection; however, you can apply a set of steps only to a single object at a time.
To apply the steps to each object in a set of objects, you must make the last step in the series select the next object in the set. The second procedure demonstrates this principle in a specific scenario: setting the vertical and horizontal spacing of a series of images.
