css-どうしてもチェックボックスの色を変更できない

Question

私はチェックボックスの背景色をスタイルしようとしますが、それは私が何をしても変更しません。最新のfirefox 29を使用しています。

CSSにルールの変更がありますか、それともブラウザにある可能性がありますか？

CSS：

input[type="checkbox"] {
    background: #990000;    
}

.chk {
   background-color: #990000;  

}

こちらがデモです http://jsfiddle.net/6KXRg/

Answer 1

チェックボックスはスタイルを設定できません。サードパーティのjsプラグインが必要になります。多くのプラグインが利用可能です。

自分でこれを行う場合は、基本的に、チェックボックスを非表示にして要素を作成し、必要に応じてクリックイベントを2つの関数にバインドし、1つは外観を変更し、もう1つはチェックボックスのクリックイベントをアクティブにします。

ドロップダウン選択要素の小さな下矢印をスタイル設定しようとすると、同じ問題が発生します。

Answer 2

質問は答えられており古いですが、チェックボックスのスタイリングの問題を克服するためのいくつかのオプションを調査する際に、背景色やその他の外観を制御するチェックボックスとラジオボタンのスタイリングのみのこの素晴らしいセットに遭遇しました。これはこの質問の路地のすぐ上かもしれないと思った。

Answer 3

同じ問題があり、大きな入力を使用しようとして、非常に小さなチェックボックスがありました。いくつかの検索の後、これは私のニーズに十分です：

input[type='checkbox']{
  width: 30px !important;
  height: 30px !important;
  margin: 5px;
  -webkit-appearance: none;
  -moz-appearance: none;
  -o-appearance: none;
  appearance:none;
  outline: 2px solid lightblue;
  box-shadow: none;
  font-size: 2em;
}

JSFiddle

誰かが役に立つと思うかもしれません。

Answer 4

技術的には、CSSを使用して任意の色を変更できます。前述のように、背景色または色を変更することはできませんが、CSSフィルターを使用できます。例えば：

input[type="checkbox"] { /* change "blue" browser chrome to yellow */
  filter: invert(100%) hue-rotate(18deg) brightness(1.7);
}

しかし、チェックボックスの設計管理を本当に探している場合、最善の策は「非表示」チェックボックスを実行し、divなどの隣接する要素をスタイルすることです。

Answer 5

そのように非常に単純化することができます：

input[type="checkbox"]{
    outline:2px solid red;
    outline-offset: -2px;
}

プラグインなしで動作します:)

Answer 6

チェックボックスの背景を変更することはできませんが、いくつかの方法でこれを試してみてください:)

.divBox {
    width: 20px;
    height: 20px;
    background: #ddd;
    margin: 20px 90px;
    position: relative;
    -webkit-box-shadow: 0px 1px 3px rgba(0,0,0,0.5);
    -moz-box-shadow: 0px 1px 3px rgba(0,0,0,0.5);
    box-shadow: 0px 1px 3px rgba(0,0,0,0.5);
}

.divBox label {
    display: block;
    width: 20px;
    height: 20px;
    -webkit-transition: all .5s ease;
    -moz-transition: all .5s ease;
    -o-transition: all .5s ease;
    -ms-transition: all .5s ease;
    transition: all .5s ease;
    cursor: pointer;
    position: absolute;
    top: 1px;
    z-index: 1;
    /* 
    use this background transparent to check the value of checkbox 
    background: transparent;
    */
    background: Black;
    -webkit-box-shadow:inset 0px 1px 3px rgba(0,0,0,0.5);
    -moz-box-shadow:inset 0px 1px 3px rgba(0,0,0,0.5);
    box-shadow:inset 0px 1px 3px rgba(0,0,0,0.5);
}

.divBox input[type=checkbox]:checked + label {
    background: green;
}

<div class="divBox">
    <input type="checkbox" value="1" id="checkboxFourInput"name="" />
    <label for="checkboxFourInput"></label>
</div>

Answer 7

多分透明性：スパン内のチェックボックス

<span style="display:inline-block; background-color:silver;padding:0px;margin:0px;height:13px; width:13px; overflow:hidden"><input type="checkbox" style="opacity:0.50;padding:0px;margin:0px" /></span>

Answer 8

ILoveTuxに同意し、あまりにも多くのもの（多くの色と背景）を適用しても何も機能しませんでしたが、ここで機能するようになりました。これらのプロパティをcssに適用します。

-webkit-appearance: none;
  -moz-appearance: none;
  -o-appearance: none;
  appearance:none;

そして、CSSスタイリングはチェックボックスで働き始めました:)

Answer 9

クラス（ブートストラップ）.form-check-inputのチェックボックスがあるとしましょう。次に、例として画像をチェックマークとして使用できます。

SCSSコード：

<input class="form-check-input" type="checkbox">

.form-check-input {
    width: 22px;
    height: 22px;
    -webkit-appearance: none;
    -moz-appearance: none;
    -o-appearance: none;
    appearance:none;
    outline: 1px solid blue;

    &:checked
    {
        background: white url('blue.svg') no-repeat; 
        background-size: 20px 20px;
        background-position: 50% 50%;
    }
}
