Utility & Helper Classes

To help streamline the design and development of this website, helper classes (classes that can be reused very very often) were installed to reduce the amount of time writing custom code when putting together a design from the team.

The classes listed in this section are not meant to be targeted with CSS to alter their styling or functionality. Instead, these classes already perform a specified action and are meant to be used with various elements when needed.

This is a quick rundown of the most used Utility & Helper Classes:


In order for pages to be structured properly, all elements must receive some type of margin or padding for adequate spacing. While this spacing is beneficial in most cases, it might be something you wish to remove or modify at other times. We have provided plenty of helper classes to use in these instances. These helper classes allow you to modify the margin and padding of elements by removing the spacing completely, or adding a small, medium, or large amount of spacing. These classes are an acronym built from three different parameters:

  1. Margin (m) or padding (p).
  2. Top (t), left (l), right (r), bottom (b), vertical (v), horizontal (h), or all (a).
  3. None (n), small (s), medium (m), or large (l).

For example, if you wanted to add a class that removed all of the margin from the top of an element you would use mtn, which stands for margin top none. Alternately, if you wanted to add a small amount of padding to both sides of an element you would use phm, which stands for padding horizontal medium.

To figure out where the spacing on an element is coming from, you can easily do this in Chrome. Simply right click on any element and select Inspect Element from the dropdown. This will reveal a popup at the bottom of your window, which will display HTML on the left and CSS on the right. You can hover over the HTML in the popup and select elements to see where any margin or padding is coming from. Margin is designated by a reddish/orange color and padding is designated by green.
