Set opacity of popup background

[Deon]

Hi

I would like to set the opacity of a popup background

I have tried this but it just makes the background completely transparent.

.ui-dialog {
background: rgb(255,0,0,0.4);
}

Hello Deon,

Please use CSS below for that:
pre.ui-popup-container div.ui-popup {
background: rgba(255,0,0,0.4);
}/pre

Thank you
Just a small mod
.ui-popup-container .ui-popup {
background: rgba(255,0,0,0.4);
}
