How to correctly create full width page
To create a full-width page in Jupiter X on the new page on the Page Attributes metabox, you should select the “Full Width” item.
This will give you a Full Width page and will remove unwanted space before and after your content. Please note that, if you want to have a full width page, it’s necessary to choose this page template. Otherwise, by removing the header and footer and title bar you will have unwanted space above and below your content.
