Article preview component with HTML CSS JavaScript

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

I have no idea what I will do next because I think in my own way there are 2 versions of the share links list, one for mobile and the other for desktop (according to 2 classes in CSS code). Therefore, I wrote JavaScript code to follow that idea.

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

• The image's not covering the whole div Solution from StackOverflow
• Button background color does not appear when the links list is active because of the stacking order in the website Solution: 4 reasons your z-index isn’t working (and how to fix it) - Jessica Chan

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

I have a problem with transition effect on the share links list that fires when the page loads, and I have no idea how to fix it.
