challenges/article-preview-component using html and css

hi, could I know how to stack absolute positioned element to top off the container(using z-index) if that container has property overflow: hidden?

in my case, ''main'' container is set to relative and has overflow hidden which leading me to a problem of stacking share_bar element on top off the screen for desktop users.

I hope, the message is clear and understandable for my all mentors and I will be glad if anybody has a suggestion for me.
