Gist of the new proposal :

Target Size (AA)

The size of the target for pointer inputs is at least 24 by 24 CSS pixels
except when:

   -

   Inline: The target is in a sentence or block of text;
   -

   User Agent Control: The size of the target is determined by the user
   agent and is not modified by the author;
   -

   Essential: A particular presentation of the target is essential to the
   information being conveyed.



NOTE : This exemption would not apply as soon as anything like font size -
and in the case of mobile/tablet browsers, viewport meta - has been
modified by the author)


Best,
Sukriti
