CSS Margin & Padding Utility

Utility for adding css classes for Margin and Padding e.g. .man for 0 margin on all sides, .ptm for 1em padding-top.

This utility plugin adds a series of css classes that allow easy addition of set padding and margin to any element.

For basic use, the classes follow the format of [margin / padding][location letter: all, top, right, bottom, left, vertical, horizontal][amount: none, small, medium, large, extra large (0.5em, 1em, 2em, 4em)]

Also in the basic classes are percentages, taking the place of the last letter in the format [p][percentage] e.g. p7-5 for 7.5% or p15 for 15%.

Examples of Basic Classes:

  • man > margin all none = margin: 0px;
  • prl > padding right large = padding-right: 2em;
  • mvp5 > margin vertical 5% = margin: 5% 0;

Additional utility classes - First / Last child

To add selective classes for adding margin / padding to the first / last child of the required element, simply add 'last-' or 'first-' to the basic classes.

Examples of Child Classes

  • last-mhxl > last-child margin horizontal extra large = last-mhxl :last-child margin: 0 4em;
  • last-pbn > last-child padding bottom none = last-pbn :last-child padding-bottom: 0;
  • first-mtm > first-child margin top medium = first-mtm :first-child margin-top: 2em;

Additional utility classes - Responsive margin / padding

You can also apply the margin / padding required to certain screen widths, ranging from xl (min: 1200px) to xs (max: 480px). To use these responsive classes, add -[screen-size] to the end of the basic classes.

Examples of Responsive Classes

  • mrm-lg > margin right medium, large screen = (max-width: 1199px) and (min-width: 980px) margin-right: 2em;
  • pas-xs > padding all small, xsmall screen = (max-width: 480px) padding: 0.5em;
  • mhp15-md > margin horizontal 15%, medium screen = (max-width: 979px) and (min-width: 768px) margin-left: 15%; margin-right: 15%;
