Radio button's appearing one over another

Question

I have custom radio buttons on my application. My issue is that currently the radio buttons display fine individually. When I try to have two of them in one line... They appear over each other instead of beside each other. I can't change my HTML and can only mess with the CSS. Any help will be appreciated. I was thinking it was due to the width of each label but giving it a low width had the same result.

HTML:

<label class="radio">
  <input type="radio">
  <span class="custom"><span>One</span></span>
</label>

CSS:

* {
  box-sizing: border-box;
}

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

label {
  cursor: pointer;
}

.radio span.custom > span {
  margin-left: 22px;
}

.radio .custom {
  background-color: #fff;
  border: 1px solid #ccc;
  border-radius: 3px;
  display: inline-block;
  height: 20px;
  left: 0;
  position: absolute;
  top: 0;
  width: 20px;
}

.radio input:checked + .custom:after {
  background-color: #0574ac;
  border-radius: 100%;
  border: 3px solid #fff;
  content: "";
  display: block;
  height: 12px;
  position: absolute;
  top: 0;
  width: 12px;
}

.radio input + .custom {
  border-radius: 100%;
}

.checkbox input:checked .custom {
  background-color: blue;
  border-color: blue;
}

just edit label class so (just example) :

label {
  cursor: pointer;
  display:inline-block;
  width: 50px;
  position:relative;
}
