/* <div class="year">S SPACING
The name of the class determines which side it is on and how many years are between the blocks.
Left are put directly beneath the right blocks, so is in relation to previous period. 
Right blocks stack on previous right blocks, so is in relation to two periods ago.

So 'left-2' is a block on the left with 2 years from the right block above it. 'right-20' would be a block to the right and 20 years beneath the right block above it.

One year equals 15 pixels.
We need to account for block height of 230px: 10yrs is 150px - 230px = -80px, 20yrs is 300px - 230px = 70px */
