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
你可以简单地使用appearance:在现代浏览器中没有,这样就没有默认样式,所有的样式都被正确应用:
input[type=checkbox] {
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
display: inline-block;
width: 2em;
height: 2em;
border: 1px solid gray;
outline: none;
vertical-align: middle;
}
input[type=checkbox]:checked {
background-color: blue;
}

这是一个CSS/HTML的版本,不需要jQuery或JavaScript,简单干净的HTML和真正简单和短的CSS。
这是JSFiddle
http://jsfiddle.net/v71kn3pr/
下面是HTML:
<div id="myContainer">
<input type="checkbox" name="myCheckbox" id="myCheckbox_01_item" value="red" />
<label for="myCheckbox_01_item" class="box"></label>
<label for="myCheckbox_01_item" class="text">I accept the Terms of Use.</label>
</div>
这是CSS
#myContainer {
outline: black dashed 1px;
width: 200px;
}
#myContainer input[type="checkbox"][name="myCheckbox"] {
display: none;
}
#myContainer input[type="checkbox"][name="myCheckbox"]:not(:checked) + label.box {
display: inline-block;
width: 25px;
height: 25px;
border: black solid 1px;
background: #FFF ;
margin: 5px 5px;
}
#myContainer input[type="checkbox"][name="myCheckbox"]:checked + label.box {
display: inline-block;
width: 25px;
height: 25px;
border: black solid 1px;
background: #F00;
margin: 5px 5px;
}
#myContainer input[type="checkbox"][name="myCheckbox"] + label + label.text {
font: normal 12px arial;
display: inline-block;
line-height: 27px;
vertical-align: top;
margin: 5px 0px;
}
这可以调整为能够有单独的单选或复选框,复选框组和单选按钮组。
这个html/css,将允许你也捕获点击标签,所以复选框将被选中和未选中,即使你只是点击标签。
这种类型的复选框/单选按钮适用于任何形式,完全没有问题。已测试使用PHP, ASP。NET (.aspx), JavaServer Faces和ColdFusion。

下面的答案参考了css3广泛可用之前的情况。在现代浏览器(包括Internet Explorer 9及更高版本)中,使用您喜欢的样式创建复选框替换更简单,而无需使用JavaScript。

It is worth noting that the fundamental issue has not changed. You still can't apply styles (borders, etc.) directly to the checkbox element and have those styles affect the display of the HTML checkbox. What has changed, however, is that it's now possible to hide the actual checkbox and replace it with a styled element of your own, using nothing but CSS. In particular, because CSS now has a widely supported :checked selector, you can make your replacement correctly reflect the checked status of the box.
年长的回答
这是一篇关于设置复选框样式的有用文章。基本上,作者发现不同浏览器的默认复选框差异很大,许多浏览器总是显示默认复选框,无论您如何设置它的样式。所以真的没有简单的方法。
不难想象,可以使用JavaScript将图像覆盖在复选框上,然后单击该图像就会选中真正的复选框。没有JavaScript的用户会看到默认的复选框。
编辑补充:这里有一个很好的脚本,为您做这件事;它隐藏了真正的复选框元素,将其替换为有样式的span,并重定向单击事件。
不,你仍然不能设置复选框本身的样式,但我(最终)想出了如何在保持单击复选框的功能的同时设置一个错觉的样式。这意味着即使光标不是完全静止,你也可以切换它,而不用冒险选择文本或触发拖放!
这个解决方案可能也适用于单选按钮。
以下内容在ie9、Firefox 30.0和Chrome 40.0.2214.91中都可以使用,这只是一个基本示例。您仍然可以将它与背景图像和伪元素结合使用。
http://jsfiddle.net/o0xo13yL/1/
label {
display: inline-block;
position: relative; /* Needed for checkbox absolute positioning */
background-color: #eee;
padding: .5rem;
border: 1px solid #000;
border-radius: .375rem;
font-family: "Courier New";
font-size: 1rem;
line-height: 1rem;
}
label > input[type="checkbox"] {
display: block;
position: absolute; /* Remove it from the flow */
width: 100%;
height: 100%;
margin: -.5rem; /* Negative the padding of label to cover the "button" */
cursor: pointer;
opacity: 0; /* Make it transparent */
z-index: 666; /* Place it on top of everything else */
}
label > input[type="checkbox"] + span {
display: inline-block;
width: 1rem;
height: 1rem;
border: 1px solid #000;
margin-right: .5rem;
}
label > input[type="checkbox"]:checked + span {
background-color: #666;
}
<label>
<input type="checkbox" />
<span> </span>Label text
</label>
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。
