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
您可以避免添加额外的标记。这适用于任何地方,除了IE通过设置CSS外观:
输入(type = "复选框"){ -webkit-appearance:没有; -moz-appearance:没有; 外观:无; /*样式复选框*/ 宽度:16 px; 高:16 px; 背景颜色:红色; } 检查输入(type = "复选框"):{ 背景颜色:绿色; } <input type="checkbox" />
其他回答
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>
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 & Conditions</label> </form>

这是一个现代版本,有一点动画,和简单的样式,你可以自定义:
.checkbox {
position: relative;
width: 20px;
height: 20px;
-webkit-appearance: none;
-moz-appearance: none;
-o-appearance: none;
appearance: none;
background: transparent;
border: 2px solid #7C7A7D;
border-radius: 5px;
margin: 0;
outline: none;
transition: 0.5s ease;
opacity: 0.8;
cursor: pointer;
}
.checkbox:checked {
border-color: #7C7A7D;
background-color: #7C7A7D;
}
.checkbox:checked:before {
position: absolute;
left: 2px;
top: -4px;
display: block;
content: '\2713';
text-align: center;
color: #FFF;
font-family: Arial;
font-size: 14px;
font-weight: 800;
}
.checkbox:hover {
opacity: 1.0;
transform: scale(1.05);
}
快速修复在文本前面添加图标:
< asp:CheckBox... Text="< img src='/link/to/img.png' />My Text" />
