CSS - How to Style a Selected Radio Buttons Label?

Question

I want to add a style to a radio button's selected label:

HTML:

<div class="radio-toolbar">
 <label><input type="radio" value="all" checked>All</label>
 <label><input type="radio" value="false">Open</label>
 <label><input type="radio" value="true">Archived</label>
</div>

CSS

.radio-toolbar input[type="radio"] {display:none;}
.radio-toolbar label {
    background:Red;
    border:1px solid green;
    padding:2px 10px;
}
.radio-toolbar label + input[type="radio"]:checked { 
    background:pink !important;
}

Any ideas what I'm doing wrong?

Answer 1

.radio-toolbar input[type="radio"] {
  display: none;
}

.radio-toolbar label {
  display: inline-block;
  background-color: #ddd;
  padding: 4px 11px;
  font-family: Arial;
  font-size: 16px;
  cursor: pointer;
}

.radio-toolbar input[type="radio"]:checked+label {
  background-color: #bbb;
}

<div class="radio-toolbar">
  <input type="radio" id="radio1" name="radios" value="all" checked>
  <label for="radio1">All</label>

  <input type="radio" id="radio2" name="radios" value="false">
  <label for="radio2">Open</label>

  <input type="radio" id="radio3" name="radios" value="true">
  <label for="radio3">Archived</label>
</div>

First of all, you probably want to add the name attribute on the radio buttons. Otherwise, they are not part of the same group, and multiple radio buttons can be checked.

Also, since I placed the labels as siblings (of the radio buttons), I had to use the id and for attributes to associate them together.
