► Selectors allow us to target elements and apply styles. We can select a large number of similar elements, or be more specific and construct rules that apply in very narrow circumstances.

In this video, we will focus on three common selector types. These are:
class selectors
ID selectors
element selectors

A class can be used as many times on a page as we like, as opposed to an ID which is used just once to uniquely identify an element, say for example a page wrapper, a navbar, or a footer. Each of which will only appear once on any given webpage.

We select IDs by referencing them by their name preceded by a hash or octothorpe (#), and we select classes by using a full stop (.) preceding the name of the class. These will select elements that have matching ID or class attributes added to their opening tags.

When selecting an HTML element we simply need to reference the element by its name (h2, div, p, nav) without anything additional added to the HTML.
