There are several editor options that you can integrate into WordPress to make designing your sites pages easy, My favourite has to be Page Builder by SiteOrigin. This plugin makes it easy to build responsive grid-based page content that adapts to mobile devices which means your page content is always displayed accurately.
It has a simple drag and drop interface and is backed up by a collection of widgets which means you shouldn’t have to modify any code. Page Builder also uses WordPress’s built in widgets and with access to some impressive plugins. This has to be one of the easiest WordPress editors available.
