[split] User guide doesn't display properly at narrow resolution

With the links provided by John the issue was apparent on Chrome too.

However, I am sure it is just a wayward media query not applying properly. It is also on my most recent firefox install too, however I am only commenting on the links provided, not having downloaded CI4 for myself yet. I am pretty sure it will be a minor thing to fix.

BTW Couldn't resist reading some of the docs for CI4, whatever their Alpha status is. Really looking forward to CI4 :-)

Best wishes,

Paul.
