css - Mediawiki1.18CSSテーブルクラス。バグ？

Question

問題：私のテーブルコードがmediawikiによって100％正しく表示されていません。内部に配置されている「親」テーブルから特定の色を誤って「継承」しているように見えます。CSSコーディングを少しシフトして正しく機能させることができるといいのですが、今のところ運がありません。

まず、mediawiki：common.cssコードを提供します。
次に、バグを示すwikiページのスクリーンショットを提供します。

第三に、スクリーンショットに示されているページのwiki構文を提供します。

すべてのスタイルで、子セレクターではなく子孫セレクターが使用されています。したがって、ネストされたテーブルは、親テーブルと同じスタイルを持つ必要があります。継承のためではなく、セレクターと一致するためです。代わりに子セレクターを使用してください。

table.Default > tbody > tr > td { color:black; border:1px solid lightgray; }

このように、子テーブルのテーブルセルはセレクターと一致しなくなります。または、セレクターをそのままにして、前のセレクターをオーバーライドする別のより強力なセレクターを定義することもできます。

table.Default table td { border: 0px none; }

CSSとマークアップのすべてを調べるのに何時間も費やすつもりはないので、これのいくつかを推測しています。問題が子テーブルが親テーブルスタイルを取得することではなく、子テーブルがそれらに対して定義されたスタイルを取得しないことである場合は、セレクターを強化する必要があります。たとえば、次のスタイルを定義している場合：

table.foo td { background-color: #ccc; }
table.bar td { background-color: #ff0; }

このマークアップで：

<table class="bar">
    <tbody>
        <tr>
            <td>
                <table class="foo">
                    <tbody>
                        <tr>
                            <td>Why am I yellow, and not gray?!</td>
                        </tr>
                    </tbody>
                </table>
            </td>
        </tr>
    </tbody>
</table>

なんで？table.bar tdセレクターが強いからです。なんで？2つのセレクターが同じ場合、ドキュメントの後半に表示されるセレクターがより強力なセレクターになります。解決策は、ドキュメントの後半で子テーブルのスタイルを移動するのと同じくらい簡単です。trただし、ミックスにaを追加するなどして、それらをもう少し明らかに強くする方がよいでしょう。

table.foo tr td { background-color: #ccc; }
table.bar td { background-color: #ff0; }
