Sidebar and content layout that never overflows, including at the tablet width
The same task, run on 27 models. Compare the outputs side by side, or open any one in a popup to inspect it.
Top result: claude-opus-4-8 (low reasoning) at 100.0% composite. Lowest: deepseek-v4-pro at 0.0%. 27 models compared on this task.
How it ran
- Each model was given the brief below in a fresh, isolated session with no access to our tools, and returned a single self-contained index.html (inline CSS and JS, no external requests, no build step).
- The rendered output was scored 1 to 5 on brief fidelity, visual design, craft, and impact by a four-family vision panel - Anthropic (Claude Opus 4.8), OpenAI (GPT-5.5), Google (Gemini 3.1 Pro), and xAI (Grok 4.3) - using one identical prompt so the scores compare. The published judge score is leave-one-family-out: a model is never scored by a judge of its own family, so same-family self-preference is removed.
The brief
Build a single self-contained HTML file (`index.html`) that renders with no build step and no network calls (inline all CSS and JS; no external fonts, scripts, or images). Build a documentation layout with two panes inside a container with id="docs-layout": - a sidebar (id="docs-sidebar") listing at least four section links, and - a content pane (id="docs-content") with an <h1> and a paragraph. Make it fully fluid so it never scrolls horizontally at any width: - on a phone (around 360px wide) the two panes stack in one column (the content pane sits below the sidebar), - on a tablet (around 768px wide) the layout must not overflow horizontally - this is the width where a fixed-pixel pane usually breaks, so size the panes fluidly, and - on a desktop (around 1440px wide) the sidebar and content sit side by side on one row. Do not pin any pane, table, or image to a fixed pixel width wider than a tablet viewport. The page must have zero horizontal overflow at each of 360px, 768px, and 1440px wide. Use plain, accessible markup.
