我的意思是,单选按钮本身由一个圆形和中心的一个点组成(当按钮被选中时)。我想改变的是两者的颜色。使用CSS可以做到这一点吗?


当前回答

正如Fred提到的,没有办法在颜色、大小等方面对单选按钮进行本地样式设置。但是您可以使用CSS Pseudo元素来设置任意给定单选按钮的冒名顶替者,并对其进行样式化。谈到JamieD所说的,关于我们如何使用:after Pseudo元素,您可以同时使用:before和:after来实现理想的外观。

这种方法的好处:

Style your radio button and also Include a label for content. Change the outer rim color and/or checked circle to any color you like. Give it a transparent look with modifications to background color property and/or optional use of the opacity property. Scale the size of your radio button. Add various drop shadow properties such as CSS drop shadow inset where needed. Blend this simple CSS/HTML trick into various Grid systems, such as Bootstrap 3.3.6, so it matches the rest of your Bootstrap components visually.

简短演示说明如下:

Set up a relative in-line block for each radio button Hide the native radio button sense there is no way to style it directly. Style and align the label Rebuilding CSS content on the :before Pseudo-element to do 2 things - style the outer rim of the radio button and set element to appear first (left of label content). You can learn basic steps on Pseudo-elements here - http://www.w3schools.com/css/css_pseudo_elements.asp If the radio button is checked, request for label to display CSS content (the styled dot in the radio button) afterwards.

HTML

<div class="radio-item">
    <input type="radio" id="ritema" name="ritem" value="ropt1">
    <label for="ritema">Option 1</label>
</div>

<div class="radio-item">
    <input type="radio" id="ritemb" name="ritem" value="ropt2">
    <label for="ritemb">Option 2</label>
</div>

CSS

.radio-item {
  display: inline-block;
  position: relative;
  padding: 0 6px;
  margin: 10px 0 0;
}

.radio-item input[type='radio'] {
  display: none;
}

.radio-item label {
  color: #666;
  font-weight: normal;
}

.radio-item label:before {
  content: " ";
  display: inline-block;
  position: relative;
  top: 5px;
  margin: 0 5px 0 0;
  width: 20px;
  height: 20px;
  border-radius: 11px;
  border: 2px solid #004c97;
  background-color: transparent;
}

.radio-item input[type=radio]:checked + label:after {
  border-radius: 11px;
  width: 12px;
  height: 12px;
  position: absolute;
  top: 9px;
  left: 10px;
  content: " ";
  display: block;
  background: #004c97;
}

总之,不需要JavaScript,图像或电池。纯CSS。

如果你使用react bootstrap Form。你可以这样做

HTML

<Form.Check
type="radio"
id="Radio-card"
label={`check me out`}
name="paymentmethod"
value="card"
/>

SCSS

.form-check {
    display: flex;
    align-items: center;
    input[type="radio"] {
    -moz-appearance: none;
    appearance: none;
          
    width: 11px;
    height: 11px;
    padding: 1px;
    background-clip: content-box;
    border: 1px solid hotpink;
    background-color: white;
    border-radius: 50%;
    }
          
    input[type="radio"]:checked {
    outline: none;
    background-color: hotpink;
    border: 1px solid hotpink;
    }
    label {
    font-size: 14px;
    font-weight: 600;
    }
}

您可以通过两种纯CSS方式实现自定义单选按钮

Via removing standard appearance using CSS appearance and applying custom appearance. Unfortunately this was doesn't work in IE. Demo: input[type="radio"] { /* remove standard background appearance */ -webkit-appearance: none; -moz-appearance: none; appearance: none; /* create custom radiobutton appearance */ display: inline-block; width: 25px; height: 25px; padding: 6px; /* background-color only for content */ background-clip: content-box; border: 2px solid #bbbbbb; background-color: #e7e6e7; border-radius: 50%; } /* appearance for checked radiobutton */ input[type="radio"]:checked { background-color: #93e026; } /* optional styles, I'm using this for centering radiobuttons */ .flex { display: flex; align-items: center; } <div class="flex"> <input type="radio" name="radio" id="radio1" /> <label for="radio1">RadioButton1</label> </div> <div class="flex"> <input type="radio" name="radio" id="radio2" /> <label for="radio2">RadioButton2</label> </div> <div class="flex"> <input type="radio" name="radio" id="radio3" /> <label for="radio3">RadioButton3</label> </div> Via hiding radiobutton and setting custom radiobutton appearance to label's pseudoselector. By the way no need for absolute positioning here (I see absolute positioning in most demos). Demo: *, *:before, *:after { box-sizing: border-box; } input[type="radio"] { display: none; } input[type="radio"]+label:before { content: ""; /* create custom radiobutton appearance */ display: inline-block; width: 25px; height: 25px; padding: 6px; margin-right: 3px; /* background-color only for content */ background-clip: content-box; border: 2px solid #bbbbbb; background-color: #e7e6e7; border-radius: 50%; } /* appearance for checked radiobutton */ input[type="radio"]:checked + label:before { background-color: #93e026; } /* optional styles, I'm using this for centering radiobuttons */ label { display: flex; align-items: center; } <input type="radio" name="radio" id="radio1" /> <label for="radio1">RadioButton1</label> <input type="radio" name="radio" id="radio2" /> <label for="radio2">RadioButton2</label> <input type="radio" name="radio" id="radio3" /> <label for="radio3">RadioButton3</label>

正如其他人所说,没有办法在所有浏览器中实现这一点,所以跨浏览器实现这一点的最好方法是使用javascript。基本上你必须把你的单选按钮变成链接(完全可自定义通过CSS)。每次点击链接都将绑定到相关的单选框,切换他的状态和其他所有状态。

简单的跨浏览器自定义单选按钮的例子

.checkbox input{ display: none; } .checkbox input:checked + label{ color: #16B67F; } .checkbox input:checked + label i{ background-image: url('http://kuzroman.com/images/jswiddler/radio-button.svg'); } .checkbox label i{ width: 15px; height: 15px; display: inline-block; background: #fff url('http://kuzroman.com/images/jswiddler/circle.svg') no-repeat 50%; background-size: 12px; position: relative; top: 1px; left: -2px; } <div class="checkbox"> <input type="radio" name="sort" value="popularity" id="sort1"> <label for="sort1"> <i></i> <span>first</span> </label> <input type="radio" name="sort" value="price" id="sort2"> <label for="sort2"> <i></i> <span>second</span> </label> </div>

只有当你的目标是基于webkit的浏览器(Chrome和Safari,也许你正在开发Chrome WebApp,谁知道…),你可以使用以下:

input[type='radio'] {
   -webkit-appearance: none;
}

然后将其设置为一个简单的HTML元素,例如应用背景图像。

使用input[type='radio']:active用于选择输入时,提供备用图形

更新:截至2018年,您可以添加以下内容以支持多个浏览器供应商:

input[type="radio"] {
  -webkit-appearance: none;
  -moz-appearance: none;
  appearance: none;
}
