Without a suitable viewport specification, a mobile browser can treat the page like a wide desktop area and reduce it. A common starting point is width=device-width together with initial-scale=1. However, the day alone makes a rigid layout not yet responsive.
Example: Recognizing the Result
Illustrative example: A mobile browser displays the page like a wide desktop view and reduces the text. The appropriate viewport specification is missing.
<meta name="viewport" content="width=device-width, initial-scale=1">Limit cause and implement correction
Once installed, check text size, navigation and horizontal scrolling on narrow views. Look for fixed widths in tables, images, and form fields. Do not unnecessarily limit the zoom possibilities of the users. A page must remain operable even with enlarged font, instead of only looking suitable for a single device width.
What makes you recognize a suitable correction
Check viewport metadata and responsive layout together. After installation on narrow devices navigation, test forms, tables and zoom.
Classification and boundaries
When is this indication not a clear error?
A viewport tag alone does not make a rigid layout mobile. Do not unnecessarily restrict the magnification by users.
