The Text box dialog includes four tabs for defining the appearance of text boxes.
Text Box: Sets the type of text wrapping and size of the text box.
Margins: Sets the margins on All sides or Left/Right and Top/Bottom. The default is pixels. The larger the number, the bigger the margins. (If you want to use inches, just enter the number in the text field followed by "in.")
Borders: Assigns border settings and styles.
Shading: Sets background color and allows placement of a background image or pattern.
