The width of the Layout Column is determined by the
layout_typefield of the Layout Container, and the Layout Column's position within the Layout Container. For example, a Layout Column with
position = 3in a Layout Container with
layout_type = 'threeColumn255025'will have a width equal to 25% of the layout. Note that this
layout_typewould be parsed as 25%, 50%, 25%, so position three in this set would be 25%.
