# --description--

A very common way to apply color to an element with CSS is with <dfn>hexadecimal</dfn> or hex values. While hex values sound complicated, they're really just another form of RGB values.

Hex color values start with a `#` character and take six characters from 0-9 and A-F. The first pair of characters represent red, the second pair represent green, and the third pair represent blue. For example, `#4B5320`.

In the `.green` class selector, set the `background-color` property to a hex color code with the values `00` for red, `FF` for green, and `00` blue.

# --hints--

Your `.green` CSS rule should have a `background-color` property set to `#00FF00`.

```js
assert.strictEqual(new __helpers.CSSHelp(document).getStyle('.green')?.backgroundColor, 'rgb(0, 255, 0)');
```
