Padding utilities

Use the following classes to quickly set a padding:

* ecl-u-pa-xxl: Extra extra large padding
* ecl-u-pa-xl: Extra large padding
* ecl-u-pa-l: Large padding
* ecl-u-pa-m: Medium padding
* ecl-u-pa-s: Small padding
* ecl-u-pa-xs: Extra small padding

You can also set a specific padding (top, right bottom, left, horizontal,
vertical), and/or a specific breakpoint.
