html - 每个浏览器的伪内容属性各不相同

Question

我正在使用自定义 CSS 来设置单选框的样式，但现在的问题是

checked radio circle is appearing at diff positions in IE11, FF36 and Chrome. Below is the illustration

用于实现此目的的 CSS 如下:

label {
    display: inline-block;
    cursor: pointer;
    position: relative;
    padding-left: 32px;
}

input[type=radio] {
    display: none;
}

label:before {
    content: "";
    display: inline-block;
    width: 23px;
    height: 22px;
    margin-right: 10px;
    position: absolute;
    left: 0;
    border:1px solid $grey;
    border-radius: 50px;
}

input[type=radio]:checked + label:before {
    content: "\25CF";
    border:1px solid $light-blue;
    color: $light-blue;
    font-size: 26px;
    text-align: center;
    line-height: 0rem;
    padding-top: 7px;
}   

任何想法请在所有浏览器中以相同的方式工作..

我改变了方法。我没有使用内容和行高，而是按如下方式切换

label:before {
content: "";
display: inline-block;
width: 20px;
height: 20px;
margin-right: 10px;
position: absolute;
padding:1px;
left: 0;
border:1px solid black;
border-radius: 50px;
}

input[type=radio]:checked + label:before {
border:1px solid blue;
background-color:blue;
box-shadow: 0 0 0 3px #fff inset;
width: 20px;
height: 20px;
}
