Instead of specifying an element’s `margin-top`, `margin-right`, `margin-bottom`, and `margin-left` attributes, you can specify them all in one line, like this: `margin: 10px 20px 10px 20px;`.
These four values work like a clock: top, right, bottom, left, and will produce the exact same result as using the side-specific margin instructions.
```css
.green-box {
background-color: green;
margin: 40px 20px 20px 40px;
}
```
