94 Cannot scale to 500%

A meta viewport element tells the browser how to control the page's dimensions and to scale, but the ability to zoom can be disabled as a result of its use.

Users with partial vision and low vision often choose to enlarge the fonts on their browser to make text on the web easier to read. The browser's viewport focus is everything visible in the browser window at a given moment. If the user maximizes the browser to full size on a high-resolution monitor, the viewport focus area is large and may include the entire web page.
