# --description--
Change the `background-color` of the canvas to `#4d0f00`.
# --hints--
You should set the `background-color` property to `#4d0f00`.
```js
const hasBackground = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style['background-color'] === 'rgb(77, 15, 0)');
assert(hasBackground);
```
Your `.canvas` element should have a `background-color` of `#4d0f00`.
```js
const canvasBackground = new __helpers.CSSHelp(document).getStyle('.canvas')?.getPropertyValue('background-color');
assert(canvasBackground === 'rgb(77, 15, 0)');
