How to Change Zone Width With SharePoint
The purpose of a Web part zone is to serve as a receptacle for Web parts. Web parts are server controls that empower users to manipulate the appearance, contents and performance of a SharePoint page directly from the browser using the "Edit Page" option from the "Site Action" menu. Web part zones group Web parts into regions on a page and add the contents of Web parts into the content database so that users can interact with Web parts directly through the browser. Adding or deleting a Web part zone and modifying zone settings cannot be accomplished through the browser interface. Instead, you must accomplish this process through SharePoint Designer.
Open SharePoint Designer and use the "Open Site" option under the "File" menu to navigate to the site where you want modify the width of a Web part zone.
Highlight the table cell that contains the Web part zone for which you want to change the width.
Place the cursor on the right border of the cell until the two-way arrow appears and expand the cell to the left or right to decrease or increase the width of the zone.
Tips & Warnings
