There are a few ways to highlight text on Facebook. You can use the “Highlight” feature, or you can use the “Mark as favorite” feature. The “Highlight” feature is easy to use. Just click on the text you want to highlight, and then select the “Highlight” option. The text will be highlighted in a blue color, and you can change the color by selecting another color from the “Color” drop-down list. The “Mark as favorite” feature is more difficult to use, but it is worth trying out. Just click on the text you want to mark as favorite, and then select the “Mark as favorite” option. The text will be marked as a favorite, and you can access this information by clicking on the “Favorites” tab at the top of your Facebook page.
