Responsive, Display (Grid, Flex), AddEventListener, querySelector

Welldone on finishing your project. Good work. Here is a few recommendations.

1. On the desktop , the part of the image to the right on the design is hidden. You need to find a way to fix it.
2. The active part on desktop is showing a small rectangle caused by the box-shadow on this class .rigth .informationFromAuthorPost .socialMedia .box on your css on line 138. You can just remove the box-shadow in that declaration.
3. You will need one more query to take of devices like tablet, you have to scroll horizontally to see the rest of the page.
