Transparent CSS background color
Solution 1:
now you can use rgba in CSS properties like this:
.class {
background: rgba(0,0,0,0.5);
}
0.5 is the transparency, change the values according to your design.

Solution 2:
Keep these three options in mind (you want #3):
1) Whole element is transparent:
visibility: hidden;
2) Whole element is somewhat transparent:
opacity: 0.0 - 1.0;
3) Just the background of the element is transparent:
background-color: transparent;
Solution 3:
yes, thats possible. just use the rgba-syntax for your background-color.
.menue {
background-color: rgba(255, 0, 0, 0.5); //semi-transparent red
}
