For some it returns the styles of element, and for others it returns completely empty styles. Steps to reproduce: Open attached HTML file (check the console for the full styles). Actual result: The width of the play button is reported as '300px', the width of the spin button as ''. Expected results: The actual width of the play button is '16px', the width of the spin button is '13px'. Build Date & Platform: Tested in Safari 5.1 and r93978 Note: I prefixed '::' to the pseudoElt string, which I think is the correct way to do it, but the results are the same with ':' and no prefix at all. 1889358 1 ahmad.saleem792 2022-08-06 05:27:25 -0700 *** Safari 15.6 on macOS 12.5 *** width of play button: 300px width of spin button: 300px etc. *** Firefox Nightly 105 *** width of play button: width of spin button: etc. *** Chrome Canary 106 *** width of play button: 300px width of spin button: 300px etc. *** This bug has been marked as a duplicate of bug 243539 *** 105529 2011-08-29 15:18:55 -0700 2011-08-29 15:18:55 -0700 HTML file demonstrating the bug getcomputedstyle.html text/html 681 marc.hoyois PCFET0NUWVBFIGh0bWw+CjxodG1sPgo8Ym9keT4KPHNjcmlwdD4KCXZhciB2aWRlbyA9IGRvY3Vt ZW50LmNyZWF0ZUVsZW1lbnQoInZpZGVvIik7Cgl2aWRlby5jb250cm9scyA9IHRydWU7Cglkb2N1 bWVudC5ib2R5LmFwcGVuZENoaWxkKHZpZGVvKTsKCXZhciBpbnB1dCA9IGRvY3VtZW50LmNyZWF0 ZUVsZW1lbnQoImlucHV0Iik7CglpbnB1dC50eXBlID0gIm51bWJlciI7Cglkb2N1bWVudC5ib2R5 LmFwcGVuZENoaWxkKGlucHV0KTsKCXZhciBzdHlsZTEgPSBnZXRDb21wdXRlZFN0eWxlKHZpZGVv LCAiOjotd2Via2l0LW1lZGlhLWNvbnRyb2xzLXBsYXktYnV0dG9uIik7Cgl2YXIgc3R5bGUyID0g Z2V0Q29tcHV0ZWRTdHlsZSh2aWRlbywgIjo6LXdlYmtpdC1pbm5lci1zcGluLWJ1dHRvbiIpOwoJ Y29uc29sZS5sb2coIlN0eWxlIG9mIHBsYXkgYnV0dG9uOiAiICsgc3R5bGUxLmNzc1RleHQpOwoJ Y29uc29sZS5sb2coIlN0eWxlIG9mIHNwaW4gYnV0dG9uOiAiICsgc3R5bGUyLmNzc1RleHQpOwoJ YWxlcnQoIndpZHRoIG9mIHBsYXkgYnV0dG9uOiAiICsgc3R5bGUxLmdldFByb3BlcnR5VmFsdWUo IndpZHRoIikgKyAiXG53aWR0aCBvZiBzcGluIGJ1dHRvbjogIiArIHN0eWxlMi5nZXRQcm9wZXJ0 eVZhbHVlKCJ3aWR0aCIpICsgIlxuZXRjLiIpOwo8L3NjcmlwdD4KPC9ib2R5Pgo8L2h0bWw+
