Content 3 block design & features
This is a multi-column reference article built with shadcn/ui: top breadcrumbs, a title row with supporting buttons, a narrow column of topic links beside a wide teaching column that mixes paragraphs, imagery, and structured inserts. The sample copy reads as a topical guide broken into sections; the sidebar tracks where you are while scrolling so the page behaves like documentation with both hierarchy and depth.
Muted backgrounds, standard text colors, and bordered tables keep the aesthetic restrained and readable. Figures sit in the flow rather than edge-to-edge hero treatments. Headings step down clearly so scanning works even without the sidebar. The sidebar highlight reinforces position without loud animation in the default presentation.
The pattern reads as editorial help or a learning center article rather than a hero-led marketing story. It is more elaborate than a single-column blog post because of the rail, breadcrumbs, and mixed body elements. To ship it you need sectioned prose, images sized for inline use, optional table data, alert copy where callouts matter, and consistent labels for the outline.
Expect the sidebar and main column to stack on small screens while breadcrumbs and actions remain usable at the top.
