+ *
+ * if you want the utility to refresh the sizes as you resize the screen, consider using a listener:

+ *
+ * @param {Array} elemCollection Html objects array
+ * @param {string} minSize Minimum size for the utility to be activated, empty for small,
+ *  md for medium, lg for large, xlg for xlarge, max for maximum
