/*
Background positioning area is 250px wide by 150px tall.
The width of the background image is 20% of 250px == 50px.
The height is rescaled to 30% of 150px == 45px.
Then, because background-repeat is set to no-repeat round, the
height is rescaled as following:
Newest height = 150px / (round [150px / 45px]);
Newest height = 150px / (round [3.33]);
Newest height = 150px / (3);
Newest height = 50px;
