Here's how you can keep a special post visible on your Facebook Timeline. Doing this will also make the post expand to widescreen, thus making it more visible.
1. Find the post on your Timeline that you want to feature.
2. Hover your cursor over the post.
3. Click the star icon that appears in the upper right of the post.
4. Your post will expand to a widescreen view and will stay visible on your Timeline.
Using the star icon makes it easy to draw attention to post that you want your friends to view and remember.
