Target IE's text size with media queries or js

Question

Is there a way to target changes selected by the user in IE's View > Text Size using media queries or similar?

So, for example, when the user changes the text size to "large" I can call something like @media (text-size: large) and apply specific styles. Could also do with any js solutions.

Answer 1

You could use JavaScript to build an in-memory element with font-size:medium and compare its width to a control element with a known font size.

You can use this information to add a class (small, large, etc.) to which you can use in your CSS.

Answer 2

There is no way knowing what the user set textsize is.
