我试图使用以下样式的复选框:

<输入类型=“checkbox”样式=“border:2px点数:00f;显示:block;背景:ff0000;”/>

但是没有应用样式。复选框仍然显示其默认样式。我如何给它指定的样式?


当前回答

下面是一个带有主题支持的示例。这是一种现代的CSS转换方法。绝对不需要JavaScript。

我得到了下面的代码链接在这条评论;在一个相关问题上。

编辑:我添加了单选按钮,maxshuty建议。

const selector = '.grid-container > .grid-row > .grid-col[data-theme="retro"]'; const main = () => { new CheckboxStyler().run(selector); new RadioStyler().run(selector); }; /* * This is only used to add the wrapper class and checkmark span to an existing DOM, * to make this CSS work. */ class AbstractInputStyler { constructor(options) { this.opts = options; } run(parentSelector) { let wrapperClass = this.opts.wrapperClass; let parent = document.querySelector(parentSelector) || document.getElementsByTagName('body')[0]; let labels = parent.querySelectorAll('label'); if (labels.length) labels.forEach(label => { if (label.querySelector(`input[type="${this.opts._inputType}"]`)) { if (!label.classList.contains(wrapperClass)) { label.classList.add(wrapperClass); label.appendChild(this.__createDefaultNode()); } } }); return this; } /* @protected */ __createDefaultNode() { let checkmark = document.createElement('span'); checkmark.className = this.opts._activeClass; return checkmark; } } class CheckboxStyler extends AbstractInputStyler { constructor(options) { super(Object.assign({ _inputType: 'checkbox', _activeClass: 'checkmark' }, CheckboxStyler.defaultOptions, options));

其他回答

这是最简单的方法,你可以选择哪个复选框来提供这种样式。

CSS:

.check-box input {
  display: none;
}

.check-box span:before {
  content: ' ';
  width: 20px;
  height: 20px;
  display: inline-block;
  background: url("unchecked.png");
}

.check-box input:checked + span:before {
  background: url("checked.png");
}

HTML:

<label class="check-box">
  <input type="checkbox">
  <span>Check box Text</span>
</label>

现在只使用CSS就可以改变所有复选框的颜色:

如前所述,当选中复选框时,最近的重音颜色CSS属性用于更改复选框的颜色。 然而,我没有看到其他人提到的是,当复选框未选中时,如果你使用CSS的过滤器属性,你可以改变背景颜色和/或边界。

对于简单的更改,您可以使用亮度将白色背景颜色变深为灰色或黑色,并使用色调旋转可以为边界赋予颜色(至少在Firefox中是这样)。然而,如果你想完全改变背景为任何颜色,你也可以用滤镜来做到这一点,但你必须做一些技巧,你将多个滤镜组合在一起,基于这个问题的方法:如何仅使用CSS滤镜将黑色转换为任何给定的颜色

幸运的是,这种复杂的方法似乎在所有浏览器中都有效,并且您可以使用生成器来计算所需的过滤器:https://codepen.io/jumarjuaton/full/mdJYWYq (这个链接是从白色转换而来的,不像上面链接的问题)

请看下面的例子:

/* Disable 'filters' while checked since they impact 'accent-color'. */ input[type='checkbox']:checked { filter: none; } input[type='radio']:checked { filter: none; } /** * We use 'accent-color' for colors in the checked stated and we use * 'filter' to change the background colors in the unchecked state. */ .red-bg-input { accent-color: red; filter: invert(85%) sepia(83%) saturate(6726%) hue-rotate(360deg) brightness(111%) contrast(111%); } .green-bg-input { accent-color: green; filter: invert(49%) sepia(65%) saturate(7149%) hue-rotate(92deg) brightness(89%) contrast(103%); } .blue-bg-input { accent-color: blue; filter: invert(30%) sepia(99%) saturate(6101%) hue-rotate(202deg) brightness(52%) contrast(136%); } .teal-bg-input { accent-color: teal; filter: invert(58%) sepia(77%) saturate(3139%) hue-rotate(157deg) brightness(89%) contrast(101%) } .dark-input { accent-color: black; filter: brightness(0%) saturate(100) hue-rotate(25deg); } .gray-input { accent-color: purple; filter: brightness(60%) saturate(100) hue-rotate(25deg); } .orange-bg-input { accent-color: orange; filter: invert(63%) sepia(28%) saturate(7249%) hue-rotate(0deg) brightness(103%) contrast(105%); } <input type="checkbox" /> <input type="checkbox" checked/> <input type="radio" /> <input type="radio" checked /> Defaults <br> <input class="red-bg-input" type="checkbox" /> <input class="red-bg-input" type="checkbox" checked/> <input class="red-bg-input" type="radio" /> <input class="red-bg-input" type="radio" checked/> Red <br> <input class="green-bg-input" type="checkbox" /> <input class="green-bg-input" type="checkbox" checked/> <input class="green-bg-input" type="radio" /> <input class="green-bg-input" type="radio" checked/> Green <br> <input class="blue-bg-input" type="checkbox" /> <input class="blue-bg-input" type="checkbox" checked/> <input class="blue-bg-input" type="radio" /> <input class="blue-bg-input" type="radio" checked/> Blue <br> <input class="teal-bg-input" type="checkbox" /> <input class="teal-bg-input" type="checkbox" checked/> <input class="teal-bg-input" type="radio" /> <input class="teal-bg-input" type="radio" checked/> Teal <br> <input class="orange-bg-input" type="checkbox" /> <input class="orange-bg-input" type="checkbox" checked/> <input class="orange-bg-input" type="radio" /> <input class="orange-bg-input" type="radio" checked/> Orange <br> <input class="dark-input" type="checkbox" /> <input class="dark-input" type="checkbox" checked/> <input class="dark-input" type="radio" /> <input class="dark-input" type="radio" checked/> Black/dark <br> <input class="gray-input" type="checkbox" /> <input class="gray-input" type="checkbox" checked/> <input class="gray-input" type="radio" /> <input class="gray-input" type="radio" checked/> Purple + Gray background

我的解决方案

input[type="checkbox"] { cursor: pointer; -webkit-appearance: none; -moz-appearance: none; appearance: none; outline: 0; background: lightgray; height: 16px; width: 16px; border: 1px solid white; } input[type="checkbox"]:checked { background: #2aa1c0; } input[type="checkbox"]:hover { filter: brightness(90%); } input[type="checkbox"]:disabled { background: #e6e6e6; opacity: 0.6; pointer-events: none; } input[type="checkbox"]:after { content: ''; position: relative; left: 40%; top: 20%; width: 15%; height: 40%; border: solid #fff; border-width: 0 2px 2px 0; transform: rotate(45deg); display: none; } input[type="checkbox"]:checked:after { display: block; } input[type="checkbox"]:disabled:after { border-color: #7b7b7b; } <input type="checkbox"><br> <input type="checkbox" checked><br> <input type="checkbox" disabled><br> <input type="checkbox" disabled checked><br>

自定义复选框与CSS (WebKit浏览器解决方案仅Chrome, Safari,移动浏览器)

<input type="checkbox" id="cardAccptance" name="cardAccptance" value="Yes">
<label for="cardAccptance" class="bold"> Save Card for Future Use</label>

CSS:

    /* The checkbox-cu */
    
    .checkbox-cu {
        display: block;
        position: relative;
        padding-left: 35px;
        margin-bottom: 0;
        cursor: pointer;
        font-size: 16px;
        -webkit-user-select: none;
        -moz-user-select: none;
        -ms-user-select: none;
        user-select: none;
    }
    
    
    /* Hide the browser's default checkbox-cu */
    
    .checkbox-cu input {
        position: absolute;
        opacity: 0;
        cursor: pointer;
        height: 0;
        width: 0;
    }
    
    
    /* Create a custom checkbox-cu */
    
    .checkmark {
        position: absolute;
        top: 4px;
        left: 0;
        height: 20px;
        width: 20px;
        background-color: #eee;
        border: 1px solid #999;
        border-radius: 0;
        box-shadow: none;
    }
    
    
    /* On mouse-over, add a grey background color */
    
    .checkbox-cu:hover input~.checkmark {
        background-color: #ccc;
    }
    
    
    /* When the checkbox-cu is checked, add a blue background */
    
    .checkbox-cu input:checked~.checkmark {
        background-color: transparent;
    }
    
    
    /* Create the checkmark/indicator (hidden when not checked) */
    
    .checkmark:after {
        content: "";
        position: absolute;
        display: none;
    }
    
    
    /* Show the checkmark when checked */
    
    .checkbox-cu input:checked~.checkmark:after {
        display: block;
    }
    
    
    /* Style the checkmark/indicator */
    
    .checkbox-cu .checkmark::after {
        left: 7px;
        top: 3px;
        width: 6px;
        height: 9px;
        border: solid #28a745;
        border-width: 0 2px 2px 0;
        -webkit-transform: rotate(45deg);
        -ms-transform: rotate(45deg);
        transform: rotate(45deg);
        z-index: 100;
    }

使用纯CSS修改复选框样式。这不需要任何JavaScript或HTML操作:

.form input[type="checkbox"]:before { display: inline-block; font: normal normal normal 14px/1 FontAwesome; font-size: inherit; text-rendering: auto; -webkit-font-smoothing: antialiased; content: "\f096"; opacity: 1 !important; margin-top: -25px; appearance: none; background: #fff; } .form input[type="checkbox"]:checked:before { content: "\f046"; } .form input[type="checkbox"] { font-size: 22px; appearance: none; -webkit-appearance: none; -moz-appearance: none; } <link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet" /> <form class="form"> <input type="checkbox" /> </form>
