How to Change the Content Width
You can control the width of the sidebar and main content. For example you would like to make the main content wider and the sidebar narrower.
Click somewhere on the template main text and under "Table Tools" click the "Layout" tab and then click "View Gridlines". Gridlines show the cell boundaries of a table on the screen. Gridlines appear only on the screen; they are never printed.
Changing the Width
Rest the cursor on the right side of the column boundary you want to move until it becomes a resize cursor , and then drag the boundary until the column is the width you want.
