Turns any (?) page from any (?) theme into full-page.
Adam from WP Crafter contributed to it; I learned about it from one of his YouTube videos.

Some CSS problems encountered on Genesis Altitude Pro using the standard Full Width template for a page with a RL&G Gallery: Namey, some of the upper page content does not display b/c the plugin’s CSS resets padding and margin.

Here’s the offending code:

.page-template-template-page-builder-php #content, 
.page-template-template-page-builder-php .content, 
.page-template-template-page-builder-php .site-inner, 
.fpt-template-generatepress.page-template-template-page-builder-php #page, 
.fpt-template.fpt-template-evolve > #wrapper, 
.fpt-template.fpt-template-evolve .content > .row, 
.fpt-template #page, 
.fpt-template, 
.fpt-template.fpt-template-storefront.page-template-template-page-builder #content .col-full {
	max-width: 100% !important;
	width: 100% !important;
	padding: 0 !important;
	margin: 0 !important;
}
