Semi-transparent style?

[LifesGreatestGift]

you'd be better off adding it to additional.css and applying it to the class of the object you want to affect. for example

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

but change navbar to the object you'd like to affect, and change the opacity to the level you'd like.
