Facebook timeline allows a number of customization, one such is highlighting an important story/post.
As in timeline, only selected posts show up. And you might want to highlight some of the important ones to show them distinctly to viewers.
To highlight a post in Facebook, do the following,
1. Locate the post that you want to highlight in your timeline. For the post, you’ll see a star button at the top-right corner, alongside pen button.
2. Click it to highlight the post. Similarly, you can highlight other posts to distinctly show them in your Facebook timeline profile.
By highlighting a post, it expands to full size as compared to smaller default size in timeline.
To undo the highlighting, just click the same star button again.
