# --description--
Target the `.foot` element with a `class` of `left`, and position it `25%` left of its parent. Then, target the `.foot` element with a `class` of `right`, and position it `25%` right of its parent.
# --hints--
`.foot.left` セレクターを使用する必要があります。
```js
assert.match(code, /\.foot\.left\s*\{/);
```
You should give `.foot.left` a `left` of `--fcc-expected--`, but found `--fcc-actual--`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.foot.left')?.left, '25%');
```
`.foot.right` セレクターを使用する必要があります。
```js
assert.match(code, /\.foot\.right\s*\{/);
```
You should give `.foot.right` a `right` of `--fcc-expected--`, but found `--fcc-actual--`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.foot.right')?.right, '25%');
```
