One Column, Full Measure

With both rails gone, col-lg-9 inside a centered row justify-content-center is the whole layout — the article gets a comfortable line length without a sidebar competing for the eye. This is the arrangement for pages where nothing should share the screen with the content: a long-form article, a legal page, a single detailed case study.

The measure stays readable without an extra column doing the work, because .section-inner already caps the page at a sensible max-width before this centered column narrows it further still.

Mixing Layouts Across One Site

Mixing layouts is the point of the set: a full-width page like this one, an article with a right rail, documentation with a left one — all three sharing the same navbar, off-canvas menu, and footer, so navigation feels seamless while each page gets the arrangement its own content wants.

• No .content-layout row — one <article>, centered, full container width up to col-lg-9
• The natural default when no rail earns its keep
• Same navbar, off-canvas menu, and footer as every layout
• Compare with left-sidebar.html and right-sidebar.html
