CSS on code

The blue color on every 2nd code sample is a bit harsh in my opinion.

class Foo < Bar
  attr_accessor :lol
  do_this_please if is_allowed_to_do_this?
  def initialize(foo, bar, *bazarz)
    raise BazarError
  end
end

Makes the code a bit harsher to read. I suggest this color: #ECF5F9

That's the same color as the one used now, but with 50% opacity on top of a white background. Looks a bit zmoother!
