Article preview component - javascript and simple animations

It was challenging for me.

I had troubles with positioning share window and adding triangle to this.

Beside this I didn't know about fill() property so I didn't know how to change color of svg, but visualdennis https://github.com/visualdenniss/frontendmentorProjects/tree/main/src/components/newbie/ArticlePreviewCard solution helped me.

A also trained javascript, in which I am not familiar still.

Beside all these troubles I also added some simple animations in CSS and I am almost happy with my result.
