为了创建额外的元素，我们可以使用:after，:before(所以我们不需要对HTML进行太多的更改)。对于单选按钮和复选框，我们可以使用:checked。我们还可以使用其他一些伪元素(例如:hover)。使用这些组合，我们可以创建一些非常酷的自定义表单。检查这个

试试这个带有过渡的css:

Demo

$DarkBrown: #292321;

$Orange: #CC3300;

div {
  margin:0 0 0.75em 0;
}

input[type="radio"] {
    display:none;
}
input[type="radio"] + label {
    color: $DarkBrown;
    font-family:Arial, sans-serif;
    font-size:14px;
}
input[type="radio"] + label span {
    display:inline-block;
    width:19px;
    height:19px;
    margin:-1px 4px 0 0;
    vertical-align:middle;
    cursor:pointer;
    -moz-border-radius:  50%;
    border-radius:  50%;
}

input[type="radio"] + label span {
     background-color:$DarkBrown;
}

input[type="radio"]:checked + label span{
     background-color:$Orange;
}

input[type="radio"] + label span,
input[type="radio"]:checked + label span {
  -webkit-transition:background-color 0.4s linear;
  -o-transition:background-color 0.4s linear;
  -moz-transition:background-color 0.4s linear;
  transition:background-color 0.4s linear;
}

Html:

<div>
  <input type="radio" id="radio01" name="radio" />
  <label for="radio01"><span></span>Radio Button 1</label>
</div>

<div>
 <input type="radio" id="radio02" name="radio" />
 <label for="radio02"><span></span>Radio Button 2</label>
</div>

一个快速的解决方法是使用:after覆盖单选按钮输入样式，但是创建自己的自定义工具包可能是一个更好的实践。

input[type='radio']:after { width: 15px; height: 15px; border-radius: 15px; top: -2px; left: -1px; position: relative; background-color: #d1d3d1; content: ''; display: inline-block; visibility: visible; border: 2px solid white; } input[type='radio']:checked:after { width: 15px; height: 15px; border-radius: 15px; top: -2px; left: -1px; position: relative; background-color: #ffa500; content: ''; display: inline-block; visibility: visible; border: 2px solid white; } <input type='radio' name="gender"/> <input type='radio' name="gender"/>

对于那些喜欢从最小示例开始开发的人来说，这里有一个简单的自定义单选按钮，它不依赖于标签:

[type="radio"] { visibility: hidden; /* hide default radio button */ /* you may need to adjust margin here, too */ } [type="radio"]::before { /* create pseudoelement */ border: 2px solid gray; /* thickness, style, color */ height: .9em; /* height adjusts with font */ width: .9em; /* width adjusts with font */ border-radius: 50%; /* make it round */ display: block; /* or flex or inline-block */ content: " "; /* won't display without this */ cursor: pointer; /* appears clickable to mouse users */ visibility: visible; /* reverse the 'hidden' above */ } [type="radio"]:checked::before { /* selected */ /* add middle dot when selected */ /* slightly bigger second value makes it smooth */ /* even more (e.g., 20% 50%) would make it fuzzy */ background: radial-gradient(gray 36%, transparent 38%); } <br> <input type="radio" name="example" id="one" value="one"> <label for="one">one</label> <br> <br> <input type="radio" name="example" id="two" value="two"> <label for="two">two</label>

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>

我构建了@klewis的代码样本的另一个分支，通过使用:before/:after伪元素和隐藏的单选输入按钮来演示纯css和渐变。

HTML:

sample radio buttons:
<div style="background:lightgrey;">
    <span class="radio-item">
        <input type="radio" id="ritema" name="ritem" class="true" value="ropt1" checked="checked">
        <label for="ritema">True</label>
    </span>

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

        content: "";
    }
        .radio-item input[type=radio]:checked:after {
