# --description--

To finish setting up the visual effect of your checkbox, set the `font-weight` property with a value of `bold`. This will increase the visibility of the checkmark.

Now that this is easier to see, change the `color` to a value of `white`. This is going to change the color of the checkmark within the checkbox when it is checked.

Lastly, alter the `line-height` to a value of `20px`.

With that, you have completed the game settings panel!

# --hints--

You should add a `font-weight` property to your combined type selector with a pseudo-class selector and pseudo-element selector of `input[type="checkbox"]:checked::after`.

```js
assert.isNotEmpty(new __helpers.CSSHelp(document).getStyle('input[type="checkbox"]:checked::after')?.fontWeight);
```

You should have a `font-weight` property with a value of `bold`.

```js
assert.strictEqual(new __helpers.CSSHelp(document).getStyle('input[type="checkbox"]:checked::after')?.fontWeight, "bold");
```

You should add a `color` property to your combined type selector with a pseudo-class selector and pseudo-element selector of `input[type="checkbox"]:checked::after`.

```js
assert.isNotEmpty(new __helpers.CSSHelp(document).getStyle('input[type="checkbox"]:checked::after')?.color);
```

You should have a `color` property with a value of `white`.

```js
assert.oneOf(new __helpers.CSSHelp(document).getStyle('input[type="checkbox"]:checked::after')?.color, ["white", "#ffffff", "rgb(255,255,255)"]);
```

You should add a `line-height` property to your combined type selector with a pseudo-class selector and pseudo-element selector of `input[type="checkbox"]:checked::after`.

```js
assert.isNotEmpty(new __helpers.CSSHelp(document).getStyle('input[type="checkbox"]:checked::after')?.lineHeight);
```

You should have a `line-height` property with a value of `20px`.

```js
assert.strictEqual(new __helpers.CSSHelp(document).getStyle('input[type="checkbox"]:checked::after')?.lineHeight, "20px");
```
