In a text box in Word, you can align text horizontally or vertically, and you can adjust the margins. Horizontal alignment determines how the left and right edges of a paragraph fit between the left and right margins of a text box, while vertical alignment determines the placement of the text between the text box's upper and lower margins. You can adjust the margins to be narrower or wider.
