This page is the mirror of Left Sidebar: the same four-column rail and eight-column article, just swapped in the markup instead of reordered with CSS. Because the rail already comes second in the HTML, it needs no order utilities at all — it simply stacks below the article on phones, in the same sequence it reads on desktop.

That makes Right Sidebar the simpler of the two builds to maintain: the DOM order and the reading order always match. Reach for it when the rail is more supplementary than navigational — related links, a short bio, a call to action — content a visitor can miss without losing the thread of the page.

No order utilities also means no surprises for screen readers — the tab order matches what's on screen at every width.

The two widgets in this rail are unchanged in structure from Left Sidebar's, just repositioned, which is the whole point of the comparison: same components, same classes, one line of markup order decides where they land.

Every layout in this set shares the same nav, feature-strip role, and footer. Use the buttons in the rail to see the sidebar lead instead of trail, or drop it altogether.
