Consider avoiding viewport values that prevent users from resizing documents Validation Error

So apparently this new rule/standard went into effect December 2016 causing this “Consider avoiding viewport values that prevent users from resizing documents” HTML5 validation error. To fix it make sure your:

*** UPDATE***

make sure you remove the following values:

  1. maximum-scale=1.0
  2. user-scalable=no
