British english or American english, HTML

Question

I was writing code and tried to align image in centre(spelled in british english)

align='centre'

above didn't work!!

There is no spelling mistake, above spelled word meaning is "middle"

when I wrote

align='center'

it worked, Does this mean HTML is written in "American English"?

EDIT after reading comments,

The thing I was worried about is, What if a developer from British background writes a renderer for web browsers such as gecko.

Does W3C or any other organisation has standard or protocol to constraint all developers to make sure they must use american english while they develop any sort of interpreter?

Answer 1

Does this mean HTML is written in "American English"?

Yes.

 align = left|center|right [CI]

However, using the align property is deprecated - consider using CSS's text-align.
