R – SiFR Only replacing content ‘above the fold’

The forceSingleLine parameter for sIFR.replace() is the easiest way to resolve this. The problem usually arises when the Flash text is wider than the HTML text, and the elements being replaced are exactly the width of the HTML text. In this case the sIFR text won't fit in the allowed space without wrapping.

Another solution is to use letter-spacing through .sIFR-active .myNavItemToBeReplaced CSS rules, to make the HTML text wider so the Flash text does fit without wrapping.

I received an email the other day asking a rather similar question, in which sIFR.activate() was invoked from inside $(document).ready(), which would break if cookies were disabled. For various reasons sIFR.activate() must be called directly.

I'm not sure if this is applicable to the situation as described in the question, but the coincidence is interesting.
