Lettering.js is an awesome lightweight plugin. It allows us to targets specific letters, words or wrap lines to create an awesome typographical effect. Lettering.js wraps the targeted element within the span but giving them different classes so that each of them can be targeted separated with different css.
At a glance one might think its not a better idea to wrap elements within the span, but used appropriately and sensibly, lettering.js let us to create an awesome effect.
