CSS Class selectors
Class Selectors like the earlier Tag Selectors are for styling your type using CSS.
Class selectors are used to style individual words, letters or sentences and are used in conjunction with Tag Selectors.
Class selectors are identified by a full stop at the front of them. e.g. .blue-big
There is 2 steps to create a class, first is to create it, then you’ll need to apply it. Class selectors can be used more than once.
