Header transparancy

Hello, I have spun installed at weddingsbykirk.com and after reading every thread i can find about the transparency issue, nothing seems to work. I have above average knowledge of html and have set all opacity to 1. I’ve also tried changing my text color with no luck. If anyone can help, i would be very appreciative.

Thanks

#masthead {
	clear: both;
	display: block;
	min-height: 30px;
	opacity: 1;
	padding: 30px 0;
	position: relative;
	transition: opacity 1s ease-in-out;
	-webkit-transition: opacity 1s ease-in-out;
	-moz-transition: opacity 1s ease-in-out;
	-o-transition: opacity 1s ease-in-out;
	width: 100%;
}
#masthead:hover {
	opacity: 1;
	transition: opacity 1s ease-in-out;
	-webkit-transition: opacity 1s ease-in-out;
	-moz-transition: opacity 1s ease-in-out;
