I am attempting to create a transparent container for my website on Google Sites in order to display the background image. Unfortunately, it seems that the opacity property of CSS3 is not supported on Google Sites. Are there any alternative methods to achieve this effect? Thank you for your help. I have already tried the following code:
filter: alpha (opacity=50); -moz-opacity: 0.50; opacity: 0.50; -khtml-opacity: 0.5; but it's not recognized.
