On this page: http://ewh.ieee.org/r1/schenectady/New/
I have two elements, "bluegradient" and "whitebox".
The bluegradient height is 80% (of the page, right?).
The whitebox height is 80% (I think this "80% of the height of the bluegradient" since it is nested, right?). The whitebox has top and bottom margins of 10% (this is 10% of the whitebox height, right?). Therefore the total whitebox should be 80 + 8 + 8 = 96% of the bluegradient height. However, a vertical scrollbar appears on the bluegradient (due to overflow: auto;) - but shouldn't the whitebox be small enough not to warrant this scrollbar?
