Responsive Article preview component

Good job, your solution is quite close from the actual design. I could pinpoint some small inaccuracies:

• The value of border-radius for the article banner needs to be changed when switching from mobile devices to desktop, from for example border-radius: 10px 10px 0 0 for mobile devices to border-radius: 10px 0 0 10px for desktop devices.
• The share button styles does not match the design given
• I think you could avoid the height changing of the card on mobile when you click on the share button by changing the margin-bottom of the .text-content and adding a margin-top for the .user-context.
