Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The x-ms-format-detection attribute determines whether data formats within the element’s text, like phone numbers, are automatically converted to followable links.
Existing links, such as ones with the tel: scheme, are unaffected.
Links created through format detection do not appear in the DOM.
This proprietary property is specific to Internet Explorer and Microsoft Edge.
Syntax
<html x-ms-format-detection="none">
