How do I adjust custom borders in Excel?

Question

In creating a custom header for a file, there is an option for aligning the left & right sections of the header w/ the page side borders; if selected, the left section is properly placed but the right is way off to the right of the page border. Is there a way to move it back to its proper position?

Answer 1

You have to adjust the right margin width.  Make the width equal to that of the left margin width so that both sides are even.
