How to Style a Selected Radio Button's Label in CSS

Radio buttons provide a unique interaction element in web interfaces, allowing users to select one option from a group. To enhance their visual appeal, it's often desirable to style the label associated with the selected radio button.

The Problem:

You've encountered a challenge while trying to apply styles to the label of a selected radio button using CSS. Your current code snippet includes the following:

.radio-toolbar label + input[type="radio"]:checked { 
    background:pink !important;
}

Identifying the Issue:

This CSS selector doesn't work because the adjacent sibling selector " " matches only the first instance of the element following it. However, in your HTML code, your labels are not immediately adjacent to the input elements.

The Solution:

To style the label of a selected radio button, the CSS selector must specifically target the label element that is associated with the checked input. This can be achieved using the 'for' attribute in the label and 'id' attribute in the respective input element, as demonstrated in the following code:

<div class="radio-toolbar">
  <input type="radio"><pre class="brush:php;toolbar:false">.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;
}

By adjusting the CSS selector, the code now correctly targets the labels of selected radio buttons and applies the desired styling.
