单选按钮的不同颜色

Question

我想用这种方式设置radion按钮的样式：

我现在的代码如下：

input[type=radio] {
display:none;
}
input[type=radio]:checked +label:before {
background:green;
width: 15px;
height: 15px;
border: 0;
border-radius: 50%;
}
label {
color:black;
font-family:arial;
font-size:12px;
position:relative;
padding-left:20px;
}
label:hover {
color:green;
}
label:hover:before {
border:1px solid green;
border-radius: 50%;
}
label:before {
content:'';
height:13px;
width:13px;
border:1px solid lightgray;
border-radius: 50%;
display:inline-block;
position:absolute;
top:0;
left:0;
}

和HTML代码：

<input id="kunstmuseum1" type="radio" name="kunstmuseum" onClick="animateKunst('voll')">    <label class="gruen" for="kunstmuseum1">Volle Subvention</label>
<input id="kunstmuseum2" type="radio" name="kunstmuseum" onClick="animateKunst('halb')"><label for="kunstmuseum2">Subventionen um die Hälfte kürzen</label>
<input id="kunstmuseum3" type="radio" name="kunstmuseum" checked="checked" onClick="animateKunst('null')"><label for="kunstmuseum3">Keine Subventionen mehr</label>

是否可以为输入[type = radio]添加不同的类，如何只填充一半的单选按钮？这是一个jsfiddle：http://jsfiddle.net/x5d4tyq7/

Answer 1

要为样式选择正确的单选按钮，请使用此css：

input[type=radio]:checked:nth-of-type(1) +label:before{

如果它处于活动状态，这将选择第一个单选按钮。将nth-of-type（1）更改为任意数字以选择正确的单选按钮。

这会将单选按钮更改为您的示例：

条纹：

  background: -webkit-repeating-linear-gradient(315deg, black, white 10%);
  background: -o-repeating-linear-gradient(315deg, black, white 10%);
  background: -moz-repeating-linear-gradient(315deg, black, white 10%);
  background: repeating-linear-gradient(315deg, black, white 10%);

50/50黑/白：

  background: -webkit-repeating-linear-gradient(90deg, black, black 49%, white 51%, white 100%);
  background: -o-repeating-linear-gradient(90deg, black, black 49%, white 51%, white 100%);
  background: -moz-repeating-linear-gradient(90deg, black, black 49%, white 51%, white 100%);
  background: repeating-linear-gradient(90deg, black, black 49%, white 51%, white 100%);

白：

  background-color: white;
  border: solid 1px green;

Here is the JSfiddle with the working code.

您可以使用线性渐变填充before

input[type=radio] {
    display:none;
}
input[type=radio]:checked +label:before {
    background: linear-gradient(to right, green 0%,green 50%, rgba(255, 255, 255, 1) 51%, rgba(255, 255,255, 1) 100%);
    /* W3C */
    width: 15px;
    height: 15px;
    border: 0;
    border-radius: 50%;
}
label {
    color:black;
    font-family:arial;
    font-size:12px;
    position:relative;
    padding-left:20px;
}
label:hover {
    color:green;
}
label:hover:before {
    border:1px solid green;
    border-radius: 50%;
}
label:before {
    content:'';
    height:13px;
    width:13px;
    border:1px solid lightgray;
    border-radius: 50%;
    display:inline-block;
    position:absolute;
    top:0;
    left:0;
}

<input id="kunstmuseum1" type="radio" name="kunstmuseum" onClick="animateKunst('voll')">
<label class="gruen" for="kunstmuseum1">Volle Subvention</label>
<input id="kunstmuseum2" type="radio" name="kunstmuseum" onClick="animateKunst('halb')">
<label for="kunstmuseum2">Subventionen um die Hälfte kürzen</label>
<input id="kunstmuseum3" type="radio" name="kunstmuseum" checked="checked" onClick="animateKunst('null')">
<label for="kunstmuseum3">Keine Subventionen mehr</label>
