I need to W3C CSS Validator logo for my website. Due to some error I m not getting it. I need your help to get them logo. Here is W3C Error List

I think all errors are same. The problem is only one opacity.

Please send me your inputs how to resolve these errors and get validate logo.

Answer 1

The way to do opacity in IE < 9 is via the non-standard filter property (it uses a Direct X filter)...there's not much you can do here, if you want opacity in IE.

If it helps, it's complaining about your properties that look like this: filter: alpha(opacity = 50); , the same for other non-standard opacity: properties.

The fact of the matter is opacity wasn't standardized early enough...and to use it is hacky, it wont validate...either accept that it won't validate or remove it from all browsers that don't support the standard opacity: property, those are the two choices available.

问题是-moz-opacity,-khtml-opacity在W3c验证程序上无效。删除它们并检查
