In what? Not a browser, obviously.
If changed to:-
var prop = document.defaultView.getComputedStyle(document.body,
'').getPropertyCSSValue('width')
var value = prop.getFloatValue(CSSPrimitiveValue.CSS_PX);
It would work in some browsers. Replacing CSS_PX with CSS_EM should
result in error.
CSS_EMS might work in some browsers.
The API is designed in a way that pretty much requires try-catch because:-
| getFloatValue
| This method is used to get a float value in a specified unit.
| If this CSS value doesn't contain a float value or can't be converted
| into the specified unit, a DOMException is raised.
It doesn't work reliably. What happens if an error is thrown?
