All solutions

I make an article Id and added it on js function parametre. This way, if there is more article on the page, the "share" button will open only the "share box" of the current article.

first time using JS, code looks like a mess. Is there any shorcuts?

What is the best way to create coloumn that take ALL horizontal space. For example here i made coloumn with 30% width and margin-right 3% to create some space beetween coloumns. But i'm not satisfied with the final results because on the preview the right side of the sections is align.

I would like to have a feedback also on my code visibility and how to choose a good name for blocks.
