Article preview component master peach, using SCSS

I had some problems with my media queries : I had to use !important for almost all my properties in this media queries (my properties did not change so put !important 😱)

This problem is not directly related to the challenge itself : it's a keyframes animation problem: I wanted that when i click on a the button, the social pannel appear and bounce (so i use keyframes) but after the animation end, and i re-click on the button the animation bug), if you have an idea to resolve this, you can answer me, and/or check my code (I commented it in the .scss file)
