css - Pourquoi ne peux-je pas changer la couleur de la case à cocher quoi que je fasse?

Question

J'essaie de styliser la couleur d'arrière-plan de la case à cocher, mais cela ne changera pas ce que je fais. J'utilise Firefox 29 plus tard.

Existe-t-il des changements de règles dans CSS ou peut-être dans le navigateur?

CSS:

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

.chk {
   background-color: #990000;  

}

Voici une démo http://jsfiddle.net/6KXRg/

Answer 1

Les cases à cocher ne peuvent pas être stylées. Vous auriez besoin d'un plugin tiers js, il en existe de nombreux.

Si vous voulez le faire vous-même, vous devez masquer la case à cocher, créer un élément et le styler à votre guise, puis lier son événement click à deux fonctions, l'une pour changer son apparence, l'autre pour activer l'événement click de la case à cocher. 

Le même problème se posera en essayant de styler cette petite flèche vers le bas sur un élément de sélection déroulant. 

Answer 2

Bien que la question ait reçu une réponse et qu’elle soit plus ancienne, en explorant quelques options pour surmonter le problème du style des cases à cocher, j’ai rencontré cet impressionnant ensemble de styles CSS3 uniquement de cases à cocher et de boutons radio contrôlant les couleurs de fond et autres apparences. Je pensais que cela pourrait être la voie à suivre pour cette question.

Answer 3

J'ai eu le même problème, en essayant d'utiliser de grandes entrées et avait une très petite case à cocher. Après quelques recherches, cela suffit pour mes besoins:

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

Peut-être que quelqu'un trouvera cela utile.

Answer 4

Techniquement, il est possible de changer la couleur de n'importe quoi avec CSS. Comme mentionné, vous ne pouvez pas changer la couleur d'arrière-plan ou la couleur mais vous pouvez utiliser des filtres CSS. Par exemple:

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

Si vous recherchez réellement un contrôle de conception sur les cases à cocher, votre meilleure option est de cocher la case "masqué" et de styler un élément adjacent tel qu'un div.

Answer 5

vous ne pouvez pas changer l'arrière-plan de la case à cocher, mais voici comment vous pouvez faire une astuce:

.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 6

Peut être très simplifié comme ça:

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

Fonctionne sans aucun plugin :)

Answer 7

La transparence peut-être: case à cocher dans la portée

<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

D'accord avec iLoveTux, appliquant trop d'éléments (beaucoup de couleurs et d'arrière-plans), rien n'a fonctionné, mais voici ce qui a commencé à fonctionner, Appliquez ces propriétés à son css:

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

et puis css styling a commencé à travailler sur la case à cocher :)
