You can achieve it if you use the position relative for the parent and absolute for the children specifically your author-social-media. But first you need to get inside the share btn and your author-social-media in one parent only so if you put position absolute in your author-social-media it will be around the parent and not in the whole body (hope gets this part). and after that you can align it now you can use negative sign let say -10px or -5px like this.
But in the arrow thing above the box you can learn about pseudo element such as :after and :before to achieve it.
If you didnt get this try to watch about position absolute and relative since they can perform complex design and also about pseudo element. good luck <3
