Unocss Preset columns

A dead-simple uno preset that adds a new unit to unocss, the "c" unit, that is equal to the size of a column.

For example, if your design has 14 columns, px-1c will generate the following styles:

.px-1c {
  padding-left: 7.1428571429vw; /* 1/14 * 100vw */
  padding-right: 7.1428571429vw;
}

The following features are supported:

• width with w-Xc

• height with h-Xc

• max-width with max-w-Xc

• max-height with max-h-Xc

• padding-left with pl-Xc

• padding-top with pt-Xc

• padding-right with pr-Xc

• padding-bottom with pb-Xc

• padding-left", "padding-right with px-Xc

• padding-top", "padding-bottom with py-Xc

• padding with p-Xc

• margin-left with ml-Xc

• margin-top with mt-Xc

• margin-right with mr-Xc

• margin-bottom with mb-Xc

• margin-left", "margin-right with mx-Xc

• margin-top", "margin-bottom with my-Xc

• margin with m-Xc

• left with left-Xc

• top with top-Xc

• right with right-Xc

• bottom with bottom-Xc
