/* The Bootstrap default grid layout is based on @media - window size
 * But in pgadmin4, we need to resize/make responsive elements based on panel size
 * which can be changed by wcDocker. Below code will generate pg-el-* classes
 * using the bootstrap grid classes generator. Based on el attribute of pg-el-container div,
 * the classes will apply.el attribute is set in /pgadmin4/web/pgadmin/browser/static/js/panel.js
 *
 * Code reused and customized from : bootstrap/scss/mixins/_grid-framework.scss
