Microsoft Visio - Formatting Calendar
You can apply common formatting techniques, such as themes and variations to a timeline. You can also select a background so that all successive timelines are created using the background template.
For example, in the Design tab, click Borders and Titles to set a professional looking that includes a title header so that all pages in that timeline have the same background and header information.
This creates a background page that overlaps all the other pages in the document.
You can also change the timeline and other shapes to make it look like a block, cylinder or support by right clicking on the mouse on the form et by selecting the corresponding type in the menu.
