Claude Code now detects viewport-fit=cover in artifact HTML so fullscreen layouts render correctly
When Claude Code renders an artifact (a generated piece of code or content, like a small web page), it now scans the artifact's HTML <meta> tags for a viewport setting containing viewport-fit=cover. New internal helpers parse the head of the document for this value, and the process that lifts information out of the artifact's head now also returns a cover true/false field alongside the existing lang field.
viewport-fit=cover is a setting web pages use to tell a browser to fill the entire screen, including areas like notches on phones. By detecting this, Claude Code can adjust how it displays an artifact so full-screen designs show up as intended instead of being boxed in or misrendered.
The finding doesn't say what Claude Code does with the detected `cover` value beyond making it available.
