I'm trying to achieve this:
I've also managed to get the result, but I cannot add the spacing between the grey border and blue circle:
input {
line-height: normal;
&[type="checkbox"],
&[type="radio"] {
width: 1.3em;
height: 1.3em;
background-color: white;
border-radius: 50%;
vertical-align: middle;
border: 1px solid #ddd;
border-width: thick;
-webkit-appearance: none;
outline: none;
cursor: pointer;
}
}

Answer 1

Use border: 2px solid white; for the white ring, and box-shadow: 0 0 0 2px #ddd; for the outer grey ring.
Then you can set background-color to white for unchecked or #73c0ec for checked.
input[type="radio"] {
width: 1.3em;
height: 1.3em;
background-color: white;
border-radius: 50%;
border: 2px solid white;
box-shadow: 0 0 0 2px #ddd;
-webkit-appearance: none;
cursor: pointer;
}
input[type="radio"]:checked {
background-color: #73c0ec;
}
<input type="radio" name="group-1"><br>
<input type="radio" name="group-1"><br>
<input type="radio" name="group-1">

Answer 2

I think you are looking for custom radio style like this
.radio-custom {
opacity: 0;
position: absolute;
}
.radio-custom, .radio-custom-label {
display: inline-block;
vertical-align: middle;
margin: 5px;
cursor: pointer;
}
.radio-custom-label {
position: relative;
}
.radio-custom + .radio-custom-label:before {
content: '';
background: #fff;
border: 2px solid #ddd;
display: inline-block;
vertical-align: middle;
width: 20px;
height: 20px;
padding: 2px;
margin-right: 10px;
text-align: center;
}
.radio-custom + .radio-custom-label:before {
border-radius: 50%;
}
.radio-custom:checked + .radio-custom-label:before {
background: #ccc;
box-shadow: inset 0px 0px 0px 4px #fff;
}
.radio-custom:focus + .radio-custom-label {
outline: 1px solid #ddd; /* focus style */
}
