This page has a DIV on it (the blue box) that has its
"style.bottom" value animated from nStart to nEnd pixels
continuously nRepeats times in a row with
steps nFrameDelay milliseconds apart,
starting nStartDelay milliseconds
after the page has finished loading.
Ideal time: nStartDelay + nFrameDelay * nRepeats * (nEnd - nStart) milliseconds.
Time taken: tDelta milliseconds. (tRatio% of ideal)
