Make content boxes and widget boxes transparent

You can adjust 0.4 to a value from 0 to 1.

#main, article {
    background-color: rgba(255, 255, 255, 0.4);
}

Man you guys are awesome. Extremely fast response. Thanks.

What about the widgets? Is there a way to make the white space transparent?

Add .sidebar .widget to the code

#main, article, .sidebar .widget {
    background-color: rgba(255, 255, 255, 0.4);
}

Awesome. Thanks again.
