CSS Question

Radio buttons are checked simultaneously

I've been trying to replicate this page https://vk.com/ You can see that they've changed the standard appearance of radio buttons in the 2nd form.

I succeeded in changing the design of the buttons but now they are all checked simultaneously.


<form class="form2">
<div class="heading">
<h2>Poprvé na VK?</h2>
<p>Okamžitá registrace</p>
<input type="text" placeholder="Vaše jméno" required>
<input type="text" placeholder="Vaše příjmení" required class="last-name">
<label class="birth">
<span>Datum narození
<i class="fa fa-question-circle-o"
<input type="date" class="date" required>
<span class="gender-head">Pohlaví</span>
<div class="gender">
<input type="radio" id="1-option" name="selector" value="female" class="control">
<div class="button"></div>Žena
<input type="radio" id="2-option" name="selector" value="male" class="control">
<div class="button"></div>Muž
<input type="radio" id="3-option" value="other" name="selector" class="control">
<div class="button"></div>Jiné
<button type="submit">Zaregistrovat se</button>
<a href="#">
<i class="fa fa-facebook-square" aria-hidden="true"></i> Přihlásit se přes Facebook</a>


form {

.gender input[type="radio"] {

.gender .button {
border: 1px solid #A3A4A6;
background: #fff;
border-radius: 50%;

width: 12px;
margin-top: 2px;
margin-right: -40px;

.gender .button:hover {
cursor: pointer;
background-color: #EAEBED;

.gender .button::before {
display: block;
content: '';
height: 6px;
width: 6px;
border-radius: 50%;

input[type="radio"]:checked ~ .button {
border: 1px solid #5A7CA3;

input[type="radio"]:checked ~ .button::before {
background: #5A7CA3;
margin: 3px 2px 2px 3px;

::-webkit-input-placeholder {
color: #7A7B7D;
padding-left: 12px;

.form2 button {
height: 20px;


I haven't learned JavaScript yet so I'd prefer CSS & HTML only solution. Thanks!


If you look at the radio buttons, by removing the position, you can see that only one is selected, and it is correct for each selection:


The problem lies in the way the presentation works. The CSS code:

input[type="radio"]:checked ~ .button::before   // Is wrong.
input[type="radio"]:checked + .button::before   // Is right.


The code given for the CSS, ~ selector is a sibling selector, which selects all the selectors.

While, what you need is the + selector, which is the immediate or adjacent sibling selector. This selects only one.

Change needs to be done here:

input[type="radio"]:checked + .button::before {
  background: #5A7CA3;
  margin: 3px 2px 2px 3px;

Note: There's an issue when you try to click on the other inputs. So, you might need to check what's blocking it. Please do not use absolute positioning without the desired result.
