+ * Box sizing utility. Convenience methods for vertical and horizontal sizing.
+ *
+ * Margin and padding utilities also allow for a pair of values that specify
+ * different sizes in both directions.
+ *
+ *
+ * Synopsis:
+ *
+ *   padding-vertical: <values>
+ *   padding-horizontal: <values>
+ *
+ *   margin-vertical: <values>
+ *   margin-horizontal: <values>
+ *
+ *   border-vertical: <values>
+ *   border-horizontal: <values>
+ *
+ *   border-width-vertical: <values>
+ *   border-width-horizontal: <values>
+ *   border-style-vertical: <values>
+ *   border-style-horizontal: <values>
+ *   border-color-vertical: <values>
+ *   border-color-horizontal: <values>
+ *
+ * Examples:
+ *
+ *     margin-horizontal: 2px
+ *     padding-veritcal: 5em 10px
+ *     border-vertical: 2px solid green
