# --description--
|
||
|
|
||
|
前回のチャレンジでは `align-items` プロパティを導入し、例を紹介しました。 このプロパティを埋め込みツイートのいくつかの要素に適用して、その中にあるフレックスアイテムを整列させることができます。
|
||
|
|
||
|
# --instructions--
|
||
|
|
||
|
CSS プロパティ `align-items` をヘッダーの `.follow-btn` 要素に追加してください。 値は `center` に設定します。
|
||
|
|
||
|
# --hints--
|
||
|
|
||
|
`.follow-btn` がページ上に表示されている必要があります。 必ず広告ブロッカーなどの拡張機能をオフにしてください。
|
||
|
|
||
|
```js
|
||
|
assert($('.follow-btn').length > 0 && $('.follow-btn').css('display') !== 'none');
|
||
|
```
|
||
|
|
||
|
`.follow-btn` 要素の `align-items` プロパティを `center` に設定してください。
|
||
|
|
||
|
```js
|
||
|
assert($('.follow-btn').css('align-items') == 'center');
|
||
|
```
