I phrased it badly when I said "minified". The HTML is available, but it's not nicely formatted - all the whitespace is gone etc. I understand this saves a few bytes but it makes life harder for anyone that tries to edit it.

It seems so strange to me that no-one else is complaining that I wonder if a nicely formatted version is available and I'm being stupid.

EDIT: This seems to have changed! Either I did something really stupid before or they have updated the HTML for the examples.
