尝试了一些交换.我直到此为止：
.radio {
margin: 0.1rem;
margin-left: 2.5rem;
margin-top:
}
.radio input[type="radio"] {
position: relative;
opacity: 0;
}
.radio input[type="radio"] + .radio-label:before {
content: '';
background: #f4f4f4;
border-radius: 100%;
border: 1px solid #b4b4b4;
display: inline-block;
width: 0.9em;
height: 0.9em;
position: relative;
/* position */
margin-right: 1em;
margin-top: -2px;
vertical-align: middle;
cursor: pointer;
text-align: center;
transition: all 250ms ease;
}
.radio input[type="radio"]:checked + .radio-label:before {
background-color: #3197EE;
box-shadow: inset 0 0 0 4px #f4f4f4;
}
.radio input[type="radio"]:focus + .radio-label:before {
outline: none;
border-color: #3197EE;
}
.radio input[type="radio"]:disabled + .radio-label:before {
box-shadow: inset 0 0 0 4px #f4f4f4;
border-color: #b4b4b4;
background: #b4b4b4;
}
.radio input[type="radio"] + .radio-label:empty:before {
margin-right: 0;
}
