Because every developer has their own preferences, and to satisfy Bulma's customization features, it's possible to specify your own class name shortcuts as well as the spacing values.
For example, if you wanted:
margin to be abbreviated to mg
padding to be totally excluded
horizontal to be abbreviated to h
vertical to be excluded as well
and to only have 3 values: "small" at 10px, "medium" at 30px, and "large" at 60px
You can simplify the CSS output by customizing these SCSS variables:

margin-left and margin-right
mgh
mgh-small
mgh-medium

By customizing the output, you've narrowed down the list of spacing helpers from 84 to only 15.
