Example: div { opacity: 0.8; filter: alpha(opacity=80); -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=80)"; } two last strings are viewed as errors, but it doesn't work on ie5-8 without them. Is it an error to use filter and -ms-filter for opacity? Thanks for your time. 74232 1 ylafon 2012-09-21 15:27:45 +0000 Yes -ms-filter is a vendor extension, and one that doesn't work well with the CSS syntax. filter is not a known CSS property. Cheers 74245 2 dexteritymaster 2012-09-21 18:53:54 +0000 Ok, fixed it with a help fix-ie-png script(or something). Thanks for fast answer by the way :D (Almost two years) By the way about "filter" as not a known CSS property http://www.w3schools.com/css/css_image_transparency.asp I always thought you were from the same company.
