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
通过使用:after和:before伪类附带的新功能,可以实现相当酷的自定义复选框效果。这样做的好处是:您不需要向DOM添加任何其他内容,只需添加标准复选框即可。
注意,这只适用于兼容的浏览器。我相信这与一些浏览器不允许你在输入元素上设置:after和:before有关。不幸的是,目前只支持WebKit浏览器。Firefox + Internet Explorer仍然允许复选框发挥作用,只是没有样式,这在未来有望改变(代码不使用供应商前缀)。
这是一个WebKit浏览器解决方案(Chrome, Safari,移动浏览器)

现代无障碍解决方案-使用重音颜色
使用新的重音-颜色属性,并确保满足适当的3:1对比度,以确保可访问性。这也适用于单选按钮。
.red-input { 颜色:# 9 d3039; 高度:20 px;/*不需要*/ 宽度:20 px;/*不需要*/ } <input class="red-input" type="checkbox" /> <!—单选按钮示例—> <input class="red-input" type="radio" />
旧的答案,我只建议如果你需要更多的定制比上述提供:
我一直在翻看这些答案,大量的答案只是将可访问性排除在门外,并以多种方式违反WCAG。我添加了单选按钮,因为大多数情况下,当你使用自定义复选框时,你也需要自定义单选按钮。

复选框-纯CSS -免费的第三方库 单选按钮-纯CSS -免费的第三方库 复选框*使用FontAwesome,但可以很容易地与Glyphicons等交换
虽然迟到了,但不知何故,在2019年、2020年和2021年,这仍然很困难,所以我添加了我的三个解决方案,它们易于使用和使用。
这些都是免费的JavaScript,可访问的,和外部库免费*…
如果你想要即插即用,只要复制样式表从fiddles,编辑CSS中的颜色代码,以适应你的需要,并在你的方式。如果需要,可以为复选框添加自定义svg复选标记图标。我为那些不喜欢css的人添加了很多注释。
如果你有很长的文本或一个小的容器,并且在复选框或单选按钮输入下遇到文本换行,那么就像这样转换为div。
更详细的解释: 我需要一个解决方案,不违反WCAG,不依赖于JavaScript或外部库,不打破键盘导航,如标签或空格键选择,允许焦点事件,一个解决方案,允许禁用复选框,既选中和未选中,最后一个解决方案,我可以自定义的复选框的外观,但我想与不同的背景颜色,边界半径,svg背景等。
我结合了@Jan turoironic的回答,想出了我自己的解决方案,看起来效果不错。我已经做了一个单选按钮小提琴,使用了许多相同的代码从复选框,以使此工作与单选按钮。
我仍然在学习无障碍,所以如果我错过了一些东西,请留下评论,我会尽量纠正它。
这是我的复选框的代码示例:
input[type="checkbox"] { position: absolute; opacity: 0; z-index: -1; } /* Text color for the label */ input[type="checkbox"]+span { cursor: pointer; font: 16px sans-serif; color: black; } /* Checkbox un-checked style */ input[type="checkbox"]+span:before { content: ''; border: 1px solid grey; border-radius: 3px; display: inline-block; width: 16px; height: 16px; margin-right: 0.5em; margin-top: 0.5em; vertical-align: -2px; } /* Checked checkbox style (in this case the background is green #e7ffba, change this to change the color) */ input[type="checkbox"]:checked+span:before { /* NOTE: Replace the url with a path to an SVG of a checkmark to get a checkmark icon */ background-image: url('https://cdnjs.cloudflare.com/ajax/libs/ionicons/4.5.6/collection/build/ionicons/svg/ios-checkmark.svg'); background-repeat: no-repeat; background-position: center; /* The size of the checkmark icon, you may/may not need this */ background-size: 25px; border-radius: 2px; background-color: #e7ffba; color: white; } /* Adding a dotted border around the active tabbed-into checkbox */ input[type="checkbox"]:focus+span:before, input[type="checkbox"]:not(:disabled)+span:hover:before { /* Visible in the full-color space */ box-shadow: 0px 0px 0px 2px rgba(0, 150, 255, 1); /* Visible in Windows high-contrast themes box-shadow will be hidden in these modes and transparency will not be hidden in high-contrast thus box-shadow will not show but the outline will providing accessibility */ outline-color: transparent; /*switch to transparent*/ outline-width: 2px; outline-style: dotted; } /* Disabled checkbox styles */ input[type="checkbox"]:disabled+span { cursor: default; color: black; opacity: 0.5; } /* Styles specific to this fiddle that you do not need */ body { padding: 1em; } h1 { font-size: 18px; } <h1> NOTE: Replace the url for the background-image in CSS with a path to an SVG in your solution or CDN. This one was found from a quick google search for a checkmark icon cdn </h1> <p>You can easily change the background color, checkbox symbol, border-radius, etc.</p> <label> <input type="checkbox"> <span>Try using tab and space</span> </label> <br> <label> <input type="checkbox" checked disabled> <span>Disabled Checked Checkbox</span> </label> <br> <label> <input type="checkbox" disabled> <span>Disabled Checkbox</span> </label> <br> <label> <input type="checkbox"> <span>Normal Checkbox</span> </label> <br> <label> <input type="checkbox"> <span>Another Normal Checkbox</span> </label>
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>
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);
}
通过使用Materialize和一个自定义样式表,你可以实现这样的东西:
CSS代码
.custom_checkbox[type="checkbox"]:checked + span:not(.lever)::before {
border: 2px solid transparent;
border-bottom: 2px solid #ffd600;
border-right: 2px solid #ffd600;
background: transparent;
}
HTML代码
<label>
<input type="checkbox" class="custom_checkbox" />
<span>Text</span>
</label>
