The style attribute names have been written in British English - e.g. the colour attribute is colour and not color as it would be in CSS.
Despite being British this drives me crazy! I use the US English spelling all the time (I've been used to it in CSS for 10+ years!) and then wonder why things arn't working.
So, +1 to no en-us to en-gb localisation. This Brit will take consistency any day :-)
At least we stuck to US English spelling of our custom HTTP "authorization" headers... lol
