This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
Using the background property shorthand, the declaration: background:transparent url(../images/buttons/showdetails.jpg) no-repeat center; Reports: Value Error : background Parse Error [empty string] But if the declaration is switched to put the horizontal position before the repeat value: background:transparent url(../images/buttons/showdetails.jpg) center no-repeat; the validator reports no error. But when it lists the valid CSS information, it shows the line with the repeat value first! (Like the code that it complained about.) Regards, Sankar R.
I've noticed this bug as well over the past two/three months. It seems to have been introduced after the last major update to the validator.
