There’s an easier way to achieve the same result. You could use Page Builder plugin. Once enabled, go to Settings > Page Builder; and ensure it’s enabled for Pages post type. Then edit your home page; switch to text mode editor; copy the content; then switch to page builder, insert a row and add a Text widget; then paste the copied content. Open the settings dialog of the row by clicking on the wrench icon.
Expand the Layout tab; scroll down and find the Row Layout dropdown; and select Full Width Stretched.
