HTML/CSS Slider Transparent Background. Help Please

[aj427]

Before you open up my website, I would like to warn that there is music that automatically plays, so you might want to turn your volume down.

1. Go to my site
2. Click view page source
3. CTR F: "slider"
4. Look at the slider CSS code.

If your too lazy to do this I will also provide the code at the bottom.

My problem: Notice how when the images go up and down the background for the box is white. I would like to make the background for this transparent. I have tried putting the Opacity to .5, however, when I do this, it changes the opacity for the images, the background, and the slider word thingy. Is there a way that I can make just the background transparent? So that you cannot see through the words or the pictures, but when they go up you can still see the background? thanks.

#s3slider {
background: none repeat scroll 0 0 #FFFFFF;
border: 3px double #CCCCCC;
height: 300px;
margin-bottom: 25px;
margin-top: 0px;
overflow: hidden;
position: relative;
text-shadow: 0 1px 0 #000000;
width: 800px;
margin: auto;
}
#s3sliderContent {
background: none repeat scroll 0 0 #FFFFFF;
height: 300px;
list-style: none outside none;
margin-left: 0;

.s3sliderImage {

}

I think this is what you want:

background-color: transparent

Thanks for warning re: music, but you should consider that your regular visitors are not getting a warning... and instead of turning the volume down, will possibly just close your site.
