trying to only show text that is not wrapped

trying to only show text that is not wrapped

I have a image and some text which sits inside the image. My problem is
when the text is wrapped because of the length I down want is displayed.
.temp-image .list .list.caption {
background-image:url(bar.png);
font-size: 16px;
font-weight: bold;
height: 30px;
left: 1px;
line-height: 16px;
overflow: hidden;
text-align: center;
top: 190px;
width: 256px;
}
