ページロード時に要素を伸縮する

Question

htmlノードを拡大し、元の状態（すべてではありませんが素敵なトランジション）に縮小するアニメーションをページロード時に作成しようとしています。目的は、オブジェクトに風船のようなエフェクトを作成し、それを元の状態に戻すことです。

私が試した解決策は、Bounce.jsを使用して要素にいくつかのキーフレームアニメーションを追加することです。私は、同じCSSプロパティを持っているが、それは動作していない両方の要素を含む子要素と子要素上で1つのアクションを実行します。

以下は、私が試したことを示すためのJSフィドルへのリンクです。この上

任意のヒントを大歓迎している:)あなたはjavascriptを経由してonloadイベントに追加されたクラスを経由して、アニメーションをトリガすることができます

。

また、元の状態に戻るように、前進1回と後退1回のアニメーションを実行する必要があります。 速記書き込みは次のようになります。

animation : animation_one 3200ms  linear     both  2     alternate; 
animation : -name   -duration -timming-fucntion  -fill-mode -iteration-count -direction ;
