Getting Started with CSS

A **CSS unit** determines the size of a property we’re setting on a page element.

We can define the `padding` on a paragraph to be `10px`, like so:

```css
p {
  padding: 10px;
}
```

The value `10px` includes the CSS unit `px` for pixel.

Is `px` the best unit to use? What about `em`, `rem`, or `vw`?

Let’s find out!
