The header and footer are not the only thing you can change for a single page. The Page settings box on any post or page carries a set of options that apply to that one page and leave every other page alone. They are presentation choices, the kind you would otherwise hand code or scope with a body class, gathered where you edit the page.
The options
Hide the title removes the title on this page and adds the lc-hide-title body class, for a landing page where your markup carries its own heading. Hide the previous and next post links drops the post navigation on a single post. Full width renders the content with no theme wrapper around it, the same passthrough idea applied to one page on demand. Noindex asks search engines not to index this page, for a thank-you page or a published draft you would rather keep out of results. Skip the site-wide head and body code leaves off the global head and body boxes here, when a page needs to run clean without your analytics or a global widget.
Hiding the archive header
One option shows only on the page you have assigned as your Posts page: hide the archive header on the blog page. Turn it on and the archive header comes off the blog index, so only the content you put above the post list shows there. It is the way to put a real introduction on your blog without the theme’s default header sitting on top of it. See How to Set Up a Blog in Loupely Canvas for where this fits.
Body classes for scoped CSS
The Body class field adds space-separated classes to the body tag on this page. It is how you scope CSS to one page from your Head code box or a stylesheet, without it leaking onto the rest of the site. Write landing dark-hero here, then write .landing .hero{ ... }, and it only ever applies where you set the class.
Page-only head and body code
Two boxes hold code for this page alone. Head code for this page prints in the head here only, for a one-off stylesheet, a meta tag, or structured data, without touching the site-wide Head box. Body end code for this page prints just before the closing body tag here only, for a page-specific script or widget. As a tag example, ＜meta name="robots" content="noindex"＞ in the page Head box does the same thing as the Noindex checkbox, if you would rather write it yourself.
Where these sit
These options share the Page settings box with the per page header and footer choice. See Per Page Header and Footer Overrides for the header and footer side of the same box.
