pseudo content properies varies in each browsers

问题

I am using custom CSS to style radio boxes but now the problem is that

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

CSS used to achieve this is as below:

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;
}   

Any ideas please to work it same in all browsers..

回答1:

I changed the approach. Instead of using content and line height, i switched as below

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;
}
