  <h2>Steps in a Range</h2>
  <p>By default, the interval between the range numbers is 1. You can change it by using the step attribute:</p>
  <form action="/action_page.php">
    <label for="customRange" class="form-label">Custom range</label>
    <input type="range" class="form-range" id="customRange" step="10" name="points">
    
    <button type="submit" class="btn btn-primary mt-3">Submit</button>
  </form>
</div>

最小值和最大值

默认情况下，最小值为 0，最大值为 100。您可以使用 min 和/或 max 属性改变它：

例子

<input type="range" class="form-range" min="0" max="4">
