title: Keeping Navigation Header at Top When Page Pulled Up on Mobile
body: <p>I've noticed on sites like <a href="https://newyorker.com" rel="nofollow noreferrer">The New Yorker</a> that when on mobile if you scroll to the very top and continue to scroll upwards the navbar stays firmly attached to the top of the window. On my site, the navbar stays connected to the rest of the content when I scroll up and continue past the body of the page. How would I go about emulating what The New Yorker does. I have looked at their page's css but can't seem to tell what gives that functionality. Any help would be appreciated.</p>
