css3 opacity google site

Question

i try to make a container for my site in google site that will be transparent so that the background image will be visible.

i guess opacity property of css3 is not supported by google sites, so is there any other way to do that? thanx i tried

filter: alpha (opacity=50); -moz-opacity: 0.50; opacity: 0.50; -khtml-opacity: 0.5; but it's not recognized.

If it allows you you can do that by applying a semi-transparent 1px x 1px .png image to the background of your container.

.yourContainer {
background:transparent url(myTransparentImage.png) repeat;
}
