A GRID BUILDER
I choose to define this plugin as a “grid builder” as opposed to a page builder, because a web page builder is normally meant as a tool that allows to create sections and, usually, comes with shortcodes which include tabs, accordions, particular sections, galleries etc… And, in lots of cases, most of these shortcodes are not well suited with other comparable plugins you choose to use.
PixGridder is alternatively very simple, as it handiest allows to cut up your page (or publish or custom post, you may decide it) in rows and columns, absolutely by transferring the features to be had on your tinyMCE editor from the whole web page to every column you make a decision
