Q: how do i add a line to the top and bottom of a text box only

Hello alegna23,

To add a line just to the top and bottom of a text box, you will need to add the two lines as shapes.  Follow the steps below to add a line to your document:

Add a shape

1. Click Shape in the toolbar.Click the arrows to see more shape styles.
2. Select a shape to add it to the page.

In step 2, select a line and use the squares on the end of the line to help resize the line.  You can find the full article here:
