これが可能かどうかわかりませんが、マップ上に半透明レイヤーを追加したいと思います。次に、レイヤー上にテキストを配置します。私は次のことを試しましたが、レイヤーはマップの後ろにあるのではなく、テキストの上にあります。どうすればこの問題を回避できますか?CSS over半透明レイヤーが機能しない

のみマップショーやブラウザに何もありません。しかし、私はそれがこのように見えるようにしたい。あなたは以下のようなあなたのメインセクションの位置を与える場合も、下図のように、単に使用レイヤーの不透明度を減らすこととは対照的に、

は、セクション#マップのinnerHTMLプロパティが上書きされた作成されます。あなたのレイヤーをセクションの外側に置きます。# –

は、あなたがして、上部と左の値を含む絶対あなたの層の位置を与えることができます代わりにあなたの背景色のrgba値:
