meta-viewport

Ensure scaling and zooming is always enabled.

Description

The user-scalable and maximum-scale parameters of the <meta name="viewport"> tag can have implications for the accessibility of a webpage, particularly for users with visual impairments or motor disabilities. Ensure scaling and zooming is possible through these parameters.

Why is it important?

Allowing users to scale content is important for users with low vision who rely on screen magnification to read text and view images more clearly. By enabling, user-scalable=yes, users can zoom in on content to make it more readable.

Setting a reasonable maximum-scale (2 or above) can ensure that content remains readable and usable at larger zoom levels. This is crucial for users with low vision who rely on high levels of magnification to access content.

How to fix?

Ensure that the following for the <meta name="viewport"> element:

• user-scalable="no" or user-scalable="0" parameter is not present.
• maximum-scale attribute is set to 2 or above.
