upsuper has just created a new issue for https://github.com/w3c/csswg-drafts: == [css-values] Value of rem when document have no root element == It is not specced that what should happen when there is no root element in a document, and one tries to compute value of `rem` unit. For example given the following code: ```html <!DOCTYPE html> <iframe src="about:blank"></iframe> <script> window.onload = function() { var win = document.querySelector('iframe').contentWindow; var doc = document.querySelector('iframe').contentDocument; var b = doc.body; doc.documentElement.style.fontSize = '24px'; b.style.lineHeight = '2rem'; doc.removeChild(doc.documentElement); alert('line-height: ' + win.getComputedStyle(b).lineHeight); }; </script> ``` Gecko and Edge shows `48px`, and Blink shows empty.
