Apply themes to your Microsoft Office Word 2007 document by using a set of theme colors, fonts and effects. There are several predefined themes from which to choose, and you can even use them in other Office programs, such as Excel and PowerPoint.

Step1 Open Word 2007. Find the "Page Layout" tab on the screen, then click "Themes."

Step2 Under "Themes," go to "Built-In" to pick one of Word's predefined document themes. Choose your formatting options such as your colors, header, body and footer text fonts, along with any line or fill effects. If you want to customize your theme, go to the "Custom" tab to apply it.

Step3 Click "Browse for Themes" on your interface if a document theme is not listed in Word. You can find and download other themes in your network or on another location on your computer. Select "Search Office Online" to pick a theme from the Microsoft Office website.

Step4 Customize your document themes. In Word 2007, go to the "Page Layout" tab, "Themes," then "Theme Colors." Choose "Create New Theme Colors" while you are still in the themes mode. Click on the button of the theme color you would like to use, then preview your changes by going to the "Sample" button.

Step5 Enter a file name in the "Name" box if you want to save your color changes, then hit "Save." Next, go back to the "Page Layout" tab, "Themes," then "Theme Fonts" to change your document's text appearance. Go to "Create New Theme Fonts" in the themes mode.

Step6 Find the "Heading Font" and "Body Font" boxes in "Themes." Pick the fonts of your choice, such as Arial or Times New Roman. Type a name for your new fonts in the "Name" box, then hit save.

Step7 Set your theme effects. At the "Page Layout" tab, go to "Themes," then choose "Theme Effects." Choose any effects such as dotted lines, color fills or three-dimensional looks. Save the changes in your document.
