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

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;
}

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。

您可以在无线电输入中嵌入span元素,然后在检查无线电输入时选择要呈现的颜色。看看下面这个来自w3schools的例子。

<!DOCTYPE html>
<html>
<style>
/* The container */
.container {
  display: block;
  position: relative;
  padding-left: 35px;
  margin-bottom: 12px;
  cursor: pointer;
  font-size: 22px;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

/* Hide the browser's default radio button */
.container input {
  position: absolute;
  opacity: 0;
  cursor: pointer;
}

/* Create a custom radio button */
.checkmark {
  position: absolute;
  top: 0;
  left: 0;
  height: 25px;
  width: 25px;
  background-color: #eee;
  border-radius: 50%;
}

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

/* When the radio button is checked, add a blue background */
.container input:checked ~ .checkmark {
  background-color: #00a80e;
}

/* Create the indicator (the dot/circle - hidden when not checked) */
.checkmark:after {
  content: "";
  position: absolute;
  display: none;
}

/* Show the indicator (dot/circle) when checked */
.container input:checked ~ .checkmark:after {
  display: block;
}

/* Style the indicator (dot/circle) */
.container .checkmark:after {
    top: 9px;
    left: 9px;
    width: 8px;
    height: 8px;
    border-radius: 50%;
    background: white;
}
</style>
<body>

<h1>Custom Radio Buttons</h1>
<label class="container">One
  <input type="radio" checked="checked" name="radio">
  <span class="checkmark"></span>
</label>
<label class="container">Two
  <input type="radio" name="radio">
  <span class="checkmark"></span>
</label>
<label class="container">Three
  <input type="radio" name="radio">
  <span class="checkmark"></span>
</label>
<label class="container">Four
  <input type="radio" name="radio">
  <span class="checkmark"></span>
</label>

</body>

在下面的代码段中改变背景颜色就可以了。

/* When the radio button is checked, add a blue background */
.container input:checked ~ .checkmark {
  background-color: #00a80e;
}

来源于如何创建自定义单选按钮

简单的方法是使用重音色

CSS属性的作用是:为某些元素生成的用户界面控件设置强调色

支持重音颜色的浏览器目前将其应用于以下HTML元素:

<input type="checkbox">
<input type="radio">
<input type="range">
<progress>

一个可运行的示例

body { display: grid; padding: 3rem 0; } .accent { accent-color: #30cc7e; } form { display: grid; grid-auto-columns: fit-content(50%); grid-template-areas: "a a"; margin: auto; padding: 0; gap: 1rem; } form { display: grid; grid-template-columns: 1fr 1fr; gap: 2rem; margin: auto; } form section:first-child { color-scheme: light; } form section:last-child { color-scheme: dark; } fieldset { border-radius: 8px; color-scheme: light; display: flex; flex: 1; flex-direction: column; gap: 1rem; padding: 1rem; } .dark { color-scheme: dark; } .dark fieldset { background: #100f33; border-color: #100f33; color: #fff; } .dark .accent { accent-color: hsla(180, 100%, 70%, 1); } h2 { margin: 0; } .notice { background: #fff9c4; border-radius: 6px; margin: 1.5rem auto; padding: 0.5rem; text-align: center; } @supports (accent-color: #fff) { .notice { display: none; } } <div class="notice"> Your browser does not support the <code>accent-color</code> property. </div> <form action=""> <fieldset> <h2>Checkboxes</h2> <div> <label for="checkbox"> Default </label> <input id="checkbox" type="checkbox" checked> </div> <div> <label for="checkbox-accent"> Accent </label> <input id="checkbox-accent" type="checkbox" class="accent" checked> </div> </fieldset> <fieldset> <h2>Radio</h2> <div> <input id="radio" type="radio" checked> <label for="radio"> Default </label> </div> <div> <input id="radio-accent" type="radio" class="accent" checked> <label for="radio-accent"> Accent </label> </div> </fieldset> <fieldset> <h2>Progress</h2> <div> <label for="progress"> Default </label> <progress id="progress" min="0" max="100" value="50"></progress> </div> <div> <label for="progress-accent"> Accent </label> <progress id="progress-accent" class="accent" min="0" max="100" value="50"></progress> </div> </fieldset> <fieldset> <h2>Range</h2> <div> <label for="range"> Default </label> <input id="range" type="range"> </div> <div> <label for="range-accent"> Accent </label> <input id="range-accent" class="accent" type="range"> </div> </fieldset> </form>

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>
