Responsive article preview component with social share links

What are you most proud of, and what would you do differently next time?

I'm pretty happy with the transitions for the display of the share links, and with the general layout of the code. There's a few things I'd like to look at doing a little differently for better consistency (like the layout of the footer of the card when the links show up). Maybe something to look at in the future.

What challenges did you encounter, and how did you overcome them?

Getting the image aligned right was a bit of a nightmare. I tried a bunch of things, most of which I don't remember, until I managed to get it looking right.

The pointy bit on the desktop view of the share links was new for me, but turned out to be pretty easy to implement.

What specific areas of your project would you like help with?

Any feedback is appreciated. Thanks!
