CSS - BAcground-color:transparent

[suarve]

Hi People,

im trying to get my style sheet to valifate without anywarnings. I have the following for example:

.sbihead
{ background: #FFF url(blue_sbi.png);
  color: #484E56;
}

.sbihead h1
{ background-color: transparent;
  color: #484E56;
}

Now i get the error: "Line : 68 (Level : 1) You have no background-color with your color : .sbihead h1". How can i sort this as the image is a gif and setting the property to "transparent" throws out the same error too

Any ideas?
