Add a border to a page
You can put a border around just one page if that page is at the beginning of a document or a section. If the page is in the middle of your document, first insert a section break.
To add the border, click Design > Page Borders:
In the Borders and Shading box, design your border:
Under Setting, choose the border style you want.
Under Style, click the line style you want.
Click the arrow under Color and choose a border color.
Click the arrow under Width and choose the width you want.
If you want a clip-art border instead, click the arrow under Art and choose a border graphic.
Next, click the arrow under Apply to and choose This section - First page only.
(This setting also works if you’re adding the border to the first page in your document.)
The Preview box confirms your border styles. To remove the border from one side, click that line in the Preview box.
Tip To change where the border appears on the page, click Options and adjust the margin settings.
