スライドショーが進行する途中で、マウスオーバーで表示される送りボタン（＜（左） ＞（右））のクリックで、スライドをその方向に進行させるとともに、スライドショーの方向もクリックした方向に切り替えるタイプのスライダーである。今回の投稿は、スライド切替時のエフェクトをフェイドイン・アウトとしている。

CSSのポイント説明
・CSSも「左右スライド移動型」とほぼ同じであるが、animation の内容が、スライドの移動（瞬間移動）とフェイドイン・アウトの記述が混在している。
・この稿も、chrome用の@frame以下の記述が省略されているので、ベンダープレフィックス(-webkit-)をつけた記述を加える必要がある。
・ちょっと記述が長くなるので、外部cssファイルにして、それにリンクさせる使い方が、他のスクリプトのclassファイル的な使い方でいいのではないかと。
