CSSグリッドレイアウト:背景色を複数のセルに広げる方法

FreeCodeCamp割り当てでは、CSSグリッドレイアウトでiOS計算機のクローンを作成しています。それを実行するJavaScriptは、後で動作します。今はデザインに力を入れています。

最終結果は次のようになります。

私がしたこと:

いくつかのネストされたグリッドで一般的なグリッドを作成しました。これらのネストされたグリッドの3番は、計算機のキー(数字0〜9、基本的な数学演算、結果、クリア)を保持する必要があります。

特定の数のcellsに継続的なbackground-colorを設定するにはどうすればよいですか。濃い灰色、オレンジなど?個人のbgdivsを設定すると、ギャップが残ります。次に、cell-bordersも例のように1pxの単色を取得します。

SOおよびCSSグリッドレイアウト/ CSS Flexboxチュートリアルで検索したところ、この明らかに単純なタスクの簡単な解決策を見つけることができませんでした。 Flexboxここに私のグリッドに?

グリッドがもたらす素晴らしい新しいダイナミクスとFlexboxとの互換性を高く評価しているのと同じくらい、私はまだ両方とも非常に新しいです。

私のコード構造に関するヒントやコメントは大歓迎です!ありがとう、クリス

  1. fixnested-3の境界線と背景にするには、次を使用して背景と境界線を設定できます。

    background: #888;
    grid-gap: 1px;
    

    すべてのchildrennested-3について、背景を設定できます。

    .nested-3 > div {
      background: #ddd;
    }
    
  2. .operationspaddingの代わりに、これをnested-3 > divに追加できます。

    .nested-3 > div {/* ADDED */
      background: #ddd;
      display: flex;
      justify-content: center;
      align-items: center;
      padding: 1.3rem;
    }
    

    また、justify-items: center divからpadding: 1remnested-3を削除する必要がある場合があります。

私もデザインを試しました-マークアップを次のように再配置しました:

<div class="nested-3 keys">
    <!-- MODIFIED HERE -->
    <div class="operations bg-grey">C</div>
    <div class="operations bg-grey">+/-</div>
    <div class="operations bg-grey">%</div>
    <div>7</div>
    <div>8</div>
    <div>9</div>
    <div>4</div>
    <div>5</div>
    <div>6</div>
    <div>1</div>
    <div>2</div>
    <div>3</div>
    <div class="zero">0</div>
    <div>.</div>
    <div class="operations bg-grey op-right">/</div>
    <div class="op-right">x</div>
    <div class="op-right">-</div>
    <div class="op-right">+</div>
    <div class="op-right">=</div>
</div>

これらのスタイルを追加しました:

.nested-3>.op-right {
  grid-column-start: 4;
  grid-row-start: 1;
  background: #fd8a0d;
}

.nested-3>.op-right+.op-right {
  grid-row-start: 2;
}

.nested-3>.op-right+.op-right+.op-right {
  grid-row-start: 3;
}

.nested-3>.op-right+.op-right+.op-right+.op-right {
  grid-row-start: 4;
}

.nested-3>.op-right+.op-right+.op-right+.op-right+.op-right {
  grid-row-start: 5;
}

.zero {
  grid-column: span 2;
}

グリッドを使用することは非常に良いですが、慎重に使用してください( https://rachelandrew.co.uk/archives/2016/03/30/should-i-use-grid-or-flexbox/ )。あなたの問題では、3つのセル(左、中央、右)にのみグリッドを使用します。しかし、私はここで「入れ子3」ボックスにFlexboxを意図的に使用しているので、試して少し遊んでみることができます。

これが役立つことを願っています!しかし、私が言ったように、小さなものにグリッドまたはフレックスを使用することが理にかなっているかどうか考えてみてください。パフォーマンスもご覧ください。

タイル枠

黒い境界線を作成する簡単な方法は、コンテナに黒い背景色を付けることです。

.nested-3 {
  background: black;
}

次に、各キーに前景色を適用します。

.nested-3 > div {
  background: #ddd;
  display: flex;
  align-items: center;
  justify-content: center;
}

(flexboxを使用してコンテンツを中央揃えにします。)

次に grid-gap 境界をシミュレートする小さな樋を作成するプロパティ。

.nested-3 {
  grid-gap: 1px;
}
