The Previous and Next post links are a powerful way to keep visitors engaged and to guide them through your site.
Elegant requires Neighbor Articles plugin to show these navigational links.
Elegant shows newer article on the right hand side and older article on the left hand side at the bottom of every article.
Most of the content on web is written in left to right languages. In these languages pages are placed from left to right. It seemed natural to use the same order in Elegant.
