Hi Kai,

my apologies for not replying earlier!
Thank you for the explanation, so it sounds like its "should just work".
After reading your explanation I realised that the html I am feeding 
into the WebView comes directly from a data base query and does not 
include the headers you see in the source of the web page.

So I suppose if I find the right CSS files and add the respective lines 
back to the downloaded html before feeding it into WebView via setHtml 
it should work?!

cssHeaders = '<head><link rel="stylesheet" 
href="/templates/yoo_sync/base.css" /></head>'

     webView.setHtml(cssHeaders + html)

Those particular css files don't give me what I'm aft so I need to dig 
up the correct one, but should this work?
