Refactor zigzag layout with CSS

[pokornyd]

Motivation

Current implementation of zigzag layout relies upon passing an incrementing index of a fact/stack component, combined with modulo to style even and odd components respectively. This is rather cumbersome and could be potentially rewritten using tailwind built-in modifiers of the same name.

Proposed solution

Rewrite zigzag layout using tailwind functionality, rather than passing down numeric prop.
