To add an opaque background to your caption:
- Select the caption by clicking on the text.
- From the Caption Tools bar that appears below the image, click on the Background box.
- Slide the bar to adjust the opacity to your liking.
This is a great way to highlight your text and make your caption stand out on the page.
