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

使用纯CSS,没有花哨的:before和:after,没有转换,您可以关闭默认外观,然后使用内联背景图像对其进行样式化,如下例所示。这适用于Chrome, Firefox, Safari,现在是Edge (Chromium Edge)。

INPUT[type=checkbox]:focus { outline: 1px solid rgba(0, 0, 0, 0.2); } INPUT[type=checkbox] { background-color: #DDD; border-radius: 2px; appearance: none; -webkit-appearance: none; -moz-appearance: none; width: 17px; height: 17px; cursor: pointer; position: relative; top: 5px; } INPUT[type=checkbox]:checked { background-color: #409fd6; background: #409fd6 url("data:image/gif;base64,R0lGODlhCwAKAIABAP////3cnSH5BAEKAAEALAAAAAALAAoAAAIUjH+AC73WHIsw0UCjglraO20PNhYAOw==") 3px 3px no-repeat; } <form> <label><input type="checkbox"> I Agree To Terms &amp; Conditions</label> </form>

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>

从我的谷歌,这是最简单的方法复选框样式。只需根据您的设计添加:after和:checked:after CSS。

body{ background: #DDD; } span{ margin-left: 30px; } input[type=checkbox] { cursor: pointer; font-size: 17px; visibility: hidden; position: absolute; top: 0; left: 0; transform: scale(1.5); } input[type=checkbox]:after { content: " "; background-color: #fff; display: inline-block; color: #00BFF0; width: 14px; height: 19px; visibility: visible; border: 1px solid #FFF; padding: 0 3px; margin: 2px 0; border-radius: 8px; box-shadow: 0 0 15px 0 rgba(0,0,0,0.08), 0 0 2px 0 rgba(0,0,0,0.16); } input[type=checkbox]:checked:after { content: "\2714"; display: unset; font-weight: bold; } <input type="checkbox"> <span>Select Text</span>

/* Hide the browser's default checkbox */
.container input {

  cursor: pointer;
  height: 0;
  width: 0;
}

/* Create a custom checkbox */
.checkmark {

  height: 25px;

  background-color: white;
  border: 2px solid red;
}

/* On mouse-over, add a grey background color */
.container:hover input ~ .checkmark {
  background-color: #ccc;
}

/* When the checkbox is checked, add a white background */
.container input:checked ~ .checkmark {
  background-color: white;
}

/* Create the checkmark/indicator (hidden when not checked) */
.checkmark:after {
  content: "";
  position: absolute;

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>
