/*
--center-page-width overrides the less variable @results-width when the results are centered
see the CSS rules for #results in style.less ( grid-template-columns and gap).

In this file, the --center-page-width values comes from the Oscar theme (Bootstrap 3).

All rules starts with ".center-alignment-yes #main_results" to be enabled only
on the /search URL and when the "center alignment" preference is enabled.
