Semi-transparent style?

[josephu]

So you suggest navigating to additional css, typing the following exactly (assuming I want to apply this effect to "navbar")

.navbar {
opacity:0.4; /* For most browsers */
filter:alpha(opacity=40); /* For IE */
}


- type that exactly?

and then what about other areas? Im not sure on all the names (should I navigate to stylevars just to find out the correct name?) Do I just type for example

.body_background {
opacity:0.4; /* For most browsers */
filter:alpha(opacity=40); /* For IE */
}

to apply this to the bodys background?

each time changing the ".XXXX" to the area I wish to apply this effect to?
