This doesn't work for rgba() and hsla() values. E.g. specifying rgba(0,0,0, .42) returns rgba(0,0,0, 0.417969) in the DOM, the same for hsla(). This is inconsistent and unexpected. 104981 1 26553 farukates 2009-01-08 17:56:19 -0800 Created attachment 26553 Same testcase file as URL: shows rgba() and opacity properties with inconsistent outcomes in the DOM Adding the testcase as a file attachment as well for scenarios where my site might possibly be down or something similar. 105007 2 mitz 2009-01-09 00:53:10 -0800 This probably happens because opacity is stored as a float and the alpha component of a color is stored as a byte. 1934900 3 ahmad.saleem792 2023-02-18 06:30:38 -0800 Using STP163, I get opacity and rgba as 0.42 in computed tab of Developer Tools?
