Highlight label if checkbox is checked

Question

Is there a non-javascript way of changing the color of a label when the corresponding checkbox is checked?

Answer 1

Use the adjacent sibling combinator:

.check-with-label:checked + .label-for-check {
  font-weight: bold;
}

<div>
  <input type="checkbox" class="check-with-label" id="idinput" />
  <label class="label-for-check" for="idinput">My Label</label>
</div>
