If you have a look at fenhamgarageservices.co.uk/floor-plans you will see the text is underline and royal blue, but my stylesheets are none and navy. Why is this not working?

I don't see underline in Chrome. It is Navy though and that comes from the css at the top of plan.html CSS for the content of the iframe will come from whatever is defined in that page, not the page in which the iframe is placed.

I am also seeing no underline in chrome.
