Refactoring

To refactor mean to change the way that the code is written with out changing it's how it behaves or what is is supposed to do.

Class composition

This is when re-used classes are put together in order to achieve a desired behaviour. Here's an example from ticket #2713

This is a custom class that I've added during the refactoring process. The existing ones are as follows:

.link--lg {
  border-top: solid 1px $ruleAndSeparatorColour; // suggestion: one class
  font-size: 20px; //
  font-weight: bold;
  line-height: 1.81818;
  padding: 10px 0; // suggestion: one class
  text-align: left;
  }
