Single-file components

Single-File Components (SFCs) are files with a .vue extension that contain the complete definition of a single component and can be imported into your Vue.js app. SFCs make it simple to create and use components, and come with a variety of other benefits which we'll soon explore.

SFCs are similar to HTML files but have (at most) three root elements: 

• template
• script
• style

The component definition goes inside the script tag and will be exactly like any other component definition except:

• It will export an ES module
• It will not need a template property (or a render function; more on that later)

The component's template will be declared as HTML markup inside the template tag. This should be a welcome relief from writing cumbersome template strings!

The style tag is a feature unique to SFCs and can contain any CSS rules you need for the component. This mostly just helps with the organization of your CSS.

Here's an example of the declaration and usage of a single-file component.
