次のようなメニューを作成するにはどうすればよいですか。
PSD画像は使いたくない。FontAwesomeなどのパッケージのアイコンを使用し、背景/CSS を CSS で生成することをお勧めします。
PSD を使用してツールチップの画像を生成し、それを使用するメニューのバージョンは、ここにあります。

ほぼ 3 年後、ようやくこれを再検討し、改良版を投稿する時間ができました。参照用に、最後に元の回答を引き続き表示できます。
特に今日は SVG の方が良い選択かもしれませんが、私の目標は、HTML と CSS だけを維持し、JS も SVG も画像も (ルート要素の背景以外は) 使用しないようにすることでした。

HTML は非常に単純です。チェックボックスハックを使用して、メニューを表示/非表示にしています。

私はこれを論理的に保ち、必要に応じて簡単に変更できるようにするために Sass を使用しています。激しくコメント。
