Missing Viewport

Warning mobile.missing_viewport

What it means

The page has no viewport meta tag, so mobile browsers render it at desktop width and scale it down.

How to fix it

Add <meta name="viewport" content="width=device-width, initial-scale=1"> to the head.

Where to find it in Truelint

Open the Issues pane on the right of the workspace and select Missing Viewport. The grid filters to every affected URL and the detail pane shows the specific finding for each. Export the list with Export → Current view, or from the API:

GET /api/v1/crawls/{handle}/issues/mobile.missing_viewport
