1) IE9 does not support JavaScript's 'const' keyword, so main.js fails, with predictable results. Changing it to 'var' fixes the problem. 2) IE9 does not wrap the list of modules: there is something about the inline display of the <li> elements that it does not like. I'm not sure what the correct fix is: a simple fix would be not to set the display to inline on IE only, so it would only display a single module per line. I'm not sure if this affects the severity, but these are not regressions: they have been present forever.

This is kind of a hacky patch, but it's the least-disruptive way I can think of to make the docs render tolerably well on IE. I've also put the static docs built with this up on to members.shaw.ca/vill/sdk

Comment on attachment 539224 [details] [diff] [review] Conditional css to make IE rendering work OK r=myk, and a=myk for commission during freeze, although drivers'll probably mark this a blocker.

Not a blocker, as it doesn't sound like a common-enough case for our developer audience, but we'll still take the patch as a low-risk ride-along.
