css in header

Hi

I am using thematic and I have created childtheme.
I have discovered that a few lines of css are being added into the head of the documents.

I want to get rid of this, but can’t seem to find where its coming from.

How would I ge rid of this – or is that a bad idea?

Thanks

Hers’s the css

<style type="text/css">
				#blog-title, #blog-title a, #blog-description {
			color:#blank;
		}
				#branding {
			background-position: center bottom;
			background-repeat: no-repeat;
			margin-top: 32px;
		}
		#blog-title, #blog-title a, #blog-description {
			display:none;
		}
		#branding {
			height:235px;
			width:940px;
			padding:0;
		}
			</style>
	</head>
