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

我总是使用伪元素:before和:after来改变复选框和单选按钮的外观。它很有魔力。

步骤

使用css规则隐藏默认复选框,如可见度:hidden或不透明度:0或位置:absolute;left:-9999px等。 使用:before元素创建一个假复选框,并传递一个空的或不间断的空格'\00a0'; 当复选框处于:checked状态时,传递unicode内容:"\2713",这是一个复选标记; 添加:焦点样式,使复选框可访问。 完成

我是这样做的。

.box { background: #666666; color: #ffffff; width: 250px; padding: 10px; margin: 1em auto; } p { margin: 1.5em 0; padding: 0; } input[type="checkbox"] { visibility: hidden; } label { cursor: pointer; } input[type="checkbox"] + label:before { border: 1px solid #333; content: "\00a0"; display: inline-block; font: 16px/1em sans-serif; height: 16px; margin: 0 .25em 0 0; padding: 0; vertical-align: top; width: 16px; } input[type="checkbox"]:checked + label:before { background: #fff; color: #333; content: "\2713"; text-align: center; } input[type="checkbox"]:checked + label:after { font-weight: bold; } input[type="checkbox"]:focus + label::before { outline: rgb(59, 153, 252) auto 5px; } <div class="content"> <div class="box"> <p> <input type="checkbox" id="c1" name="cb"> <label for="c1">Option 01</label> </p> <p> <input type="checkbox" id="c2" name="cb"> <label for="c2">Option 02</label> </p> <p> <input type="checkbox" id="c3" name="cb"> <label for="c3">Option 03</label> </p> </div> </div>

更时尚的用法:before和after

body{ font-family: sans-serif; } .container { margin-top: 50px; margin-left: 20px; margin-right: 20px; } .checkbox { width: 100%; margin: 15px auto; position: relative; display: block; } .checkbox input[type="checkbox"] { width: auto; opacity: 0.00000001; position: absolute; left: 0; margin-left: -20px; } .checkbox label { position: relative; } .checkbox label:before { content: ''; position: absolute; left: 0; top: 0; margin: 4px; width: 22px; height: 22px; transition: transform 0.28s ease; border-radius: 3px; border: 2px solid #7bbe72; } .checkbox label:after { content: ''; display: block; width: 10px; height: 5px; border-bottom: 2px solid #7bbe72; border-left: 2px solid #7bbe72; -webkit-transform: rotate(-45deg) scale(0); transform: rotate(-45deg) scale(0); transition: transform ease 0.25s; will-change: transform; position: absolute; top: 12px; left: 10px; } .checkbox input[type="checkbox"]:checked ~ label::before { color: #7bbe72; } .checkbox input[type="checkbox"]:checked ~ label::after { -webkit-transform: rotate(-45deg) scale(1); transform: rotate(-45deg) scale(1); } .checkbox label { min-height: 34px; display: block; padding-left: 40px; margin-bottom: 0; font-weight: normal; cursor: pointer; vertical-align: sub; } .checkbox label span { position: absolute; top: 50%; -webkit-transform: translateY(-50%); transform: translateY(-50%); } .checkbox input[type="checkbox"]:focus + label::before { outline: 0; } <div class="container"> <div class="checkbox"> <input type="checkbox" id="checkbox" name="" value=""> <label for="checkbox"><span>Checkbox</span></label> </div> <div class="checkbox"> <input type="checkbox" id="checkbox2" name="" value=""> <label for="checkbox2"><span>Checkbox</span></label> </div> </div>

其他回答

我会听从SW4的建议。现在不是了:Volomike的答案比这里的所有答案都要好得多(注意我在回答的评论中建议的改进)。继续阅读这个答案,如果你对这个答案所评论的其他方法感到好奇。


首先,隐藏复选框并用自定义span覆盖它,建议使用以下HTML:

<label>
  <input type="checkbox">
  <span>send newsletter</span>
</label>

标签的包装整齐地允许点击文本,而不需要“for-id”属性链接。然而,

不要使用visibility: hidden或display: none隐藏它

它通过点击或点击来工作,但这是使用复选框的蹩脚方式。有些人仍然使用更有效的Tab键来移动焦点,Space键来激活,用这种方法隐藏会禁用它。如果表单很长,可以节省一些时间来使用tabindex或accesskey属性。如果你观察系统复选框的行为,有一个不错的阴影悬停。样式良好的复选框应该遵循此行为。

cobberboy的答案是推荐字体Awesome,它通常比位图更好,因为字体是可伸缩的向量。使用上面的HTML,我建议以下CSS规则:

Hide checkboxes input[type="checkbox"] { position: absolute; opacity: 0; z-index: -1; } I use just negative z-index since my example uses big enough checkbox skin to cover it fully. I don't recommend left: -999px since it is not reusable in every layout. Bushan wagh's answer provides a bulletproof way to hide it and convince the browser to use tabindex, so it is a good alternative. Anyway, both is just a hack. The proper way today is appearance: none, see Joost's answer: input[type="checkbox"] { appearance: none; -webkit-appearance: none; -moz-appearance: none; } Style checkbox label input[type="checkbox"] + span { font: 16pt sans-serif; color: #000; } Add checkbox skin input[type="checkbox"] + span:before { font: 16pt FontAwesome; content: '\00f096'; display: inline-block; width: 16pt; padding: 2px 0 0 3px; margin-right: 0.5em; }

\00f096是fontawesome的方形,填充被调整为在焦点上提供均匀的虚线轮廓(见下文)。

添加复选框选中的皮肤 Input [type="checkbox"]:已检查+ span:before { 内容:“\ 00 f046”; }

\00f046是Font Awesome的check-square-o,它和square-o的宽度不一样,这就是上面width样式的原因。

添加焦点轮廓 Input [type="checkbox"]:焦点+ span:before { 轮廓:1px虚线#aaa; } Safari不提供这个功能(参见@Jason Sankey的评论),只支持Safari的CSS 为禁用复选框设置灰色 Input [type="checkbox"]:disabled + span { 颜色:# 999; } 在非禁用复选框上设置悬停阴影 Input [type="checkbox"]:not(:禁用)+ span:hover:before { text-shadow: 0 1px 2px #77F; }


Test it on JS Fiddle

Try to hover the mouse over the checkboxes and use Tab and Shift+Tab to move and Space to toggle.

input[type=checkbox].css-checkbox {
    position: absolute;
    overflow: hidden;
    clip: rect(0 0 0 0);
    height: 1px;
    width: 1px;
    margin: -1px;
    padding: 0;
    border: 0;
}

input[type=checkbox].css-checkbox + label.css-label {
    padding-left: 20px;
    height: 15px;
    display: inline-block;
    line-height: 15px;
    background-repeat: no-repeat;
    background-position: 0 0;
    font-size: 15px;
    vertical-align: middle;
    cursor: pointer;
}

input[type=checkbox].css-checkbox:checked + label.css-label {
    background-position: 0 -15px;
}

.css-label{
    background-image:url(http://csscheckbox.com/checkboxes/dark-check-green.png);
}

SCSS / SASS实现

更现代的方法

对于使用SCSS(或容易转换为SASS)的人来说,下面的内容将会有所帮助。有效地,在复选框旁边创建一个元素,这就是您要设置样式的元素。当单击复选框时,CSS重新设置姐妹元素的样式(为您选中的新样式)。代码如下:

label.checkbox { input[type="checkbox"] { visibility: hidden; display: block; height: 0; width: 0; position: absolute; overflow: hidden; &:checked + span { background: $accent; } } span { cursor: pointer; height: 15px; width: 15px; border: 1px solid $accent; border-radius: 2px; display: inline-block; transition: all 0.2s $interpol; } } <label class="checkbox"> <input type="checkbox" /> <span></span> Label text </label>

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 {

        top: 4px;
        left: 0;

        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;
    }

    .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);
