How to Style a Checked Radio Button's Label with CSS?

CSS Selector for Labeling Checked Radio Buttons

The question arises: is it possible to style a label associated with a checked radio button using CSS? Despite the expectations, the selector "label:checked" fails to produce the desired result.

A viable solution lies in employing the adjacent sibling combinator " ". This combinator links two sequences of selectors that share a common parent, with the second selector immediately following the first.

For instance, the selector "input[type="radio"]:checked label" targets labels that directly follow checked radio inputs, regardless of their place within the HTML structure.

Example:

input[type="radio"]:checked+label { font-weight: bold; }

HTML:

<input>

This approach effectively boldens the label of the checked radio button while leaving the labels of unchecked buttons unaffected.
