Try the following, add these methods to WAHtmlRoot

styleElementWithHref: anUrlString titled: aTitleString media: aMediaString
	^(self styleElementWithHref: anUrlString)
		attributeAt: 'title' put: aTitleString;
		attributeAt: 'media' put: aMediaString;

linkToStyle: url titled: aString media: aMediaString
	self addHeadElement:
			styleElementWithHref: (self absoluteUrlForResource: url asString)
			titled: aString
			 media: aMediaString)

then in your root component class:

updateRoot: anHtmlRoot
	super updateRoot: anHtmlRoot.
	anHtmlRoot linkToStyle: 'styles/bare.css' titled: 'Bare' media:
'screen, projection'.
	anHtmlRoot linkToStyle: 'styles/blue.css' titled: 'Blue' media:
'screen, projection'.
	anHtmlRoot linkToStyle: 'styles/styleswitch.js'

Damn we need the canvas api for head elements too.
