lizbutler on "[Twenty Twelve] Child Theme width not working on iPhone"

I am now using an HTML image. The logo disappeared on mobile and still hangs to the far left on desktop. Here is the updated code:

#logo {
	height: 169px;
	clear: both;
	margin-top: 0;
	margin-bottom: 50px;
	margin-left: auto;
	margin-right: auto;
}
