Hi Treboremac,

Adding a border to one column in a two column document is pretty easy. Here are the steps:

1. Select the column that you want to add a border to. To do this, click anywhere in the column to make sure it's selected.
2. Go to the "Page Layout" tab in the ribbon at the top of the screen.
3. Click on the "Page Borders" button in the "Page Background" section of the ribbon.
4. In the "Borders and Shading" window that appears, click on the "Borders" tab.
5. Under "Setting," select "Custom" from the drop-down menu.
6. Under "Style," select the type of border you want to add.
7. Under "Color," select the color you want the border to be.
8. Under "Width," select the width of the border.
9. Under "Preview," select the sides of the column that you want to add the border to. For example, if you want to add a border to the left side of the column, select the left side in the preview.
10. Click "OK" to apply the border to the selected column.

To add background color to the column, you can follow these steps:

1. Select the column that you want to add background color to.
2. Go to the "Page Layout" tab in the ribbon at the top of the screen.
3. Click on the "Page Color" button in the "Page Background" section of the ribbon.
4. Select the color that you want to use as the background color for the column.

That's it! Your selected column should now have a border and background color.
