You can add a span to your html and css .
Here's an example from my code ...
HTML ( JSX ):
<input type="radio" name="AMPM" id="radiostyle1" value="AM" checked={this.state.AMPM==="AM"} onChange={this.handleChange}/>
<label for="radiostyle1"><span></span> am </label>
<input type="radio" name="AMPM" id="radiostyle2" value="PM" checked={this.state.AMPM==="PM"} onChange={this.handleChange}/>
<label for="radiostyle2"><span></span> pm </label>
CSS to make standard radio button vanish on screen and superimpose custom button image:
input[type="radio"] {
opacity:0;
}
input[type="radio"] + label {
font-size:1em;
text-transform: uppercase;
color: white ;
cursor: pointer;
margin:auto 15px auto auto;
}
input[type="radio"] + label span {
display:inline-block;
width:30px;
height:10px;
margin:1px 0px 0 -30px;
cursor:pointer;
border-radius: 20%;
}
input[type="radio"] + label span {
background-color: #FFFFFF
}
input[type="radio"]:checked + label span{
background-color: #660006;
}
