纯CSS制作一个评星组件（说出去都没人信）

<div class="radio-stars">
  <input class="sr-only" id="radio-5" type="radio" name="radio-star" value="5" />
  <label class="radio-star" for="radio-5">5</label>
  <input class="sr-only" id="radio-4" type="radio" name="radio-star" value="4" checked="checked" />
  <label class="radio-star" for="radio-4">4</label>
  <input class="sr-only" id="radio-3" type="radio" name="radio-star" value="3" />
  <label class="radio-star" for="radio-3">3</label>
  <input class="sr-only" id="radio-2" type="radio" name="radio-star" value="2" />
  <label class="radio-star" for="radio-2">2</label>
  <input class="sr-only" id="radio-1" type="radio" name="radio-star" value="1" />
  <label class="radio-star" for="radio-1">1</label>
  <span class="radio-star-total"></span>
</div>
