锚中的FontAwesome图标更适合内容

我试图在列表项的右侧有两个可单击的图标。但是，由于某些原因，包含图标的锚点会延伸得很宽（没有填充或边距），从而使单击区域重叠。

这是我的字体图标问题吗？还是我找不到其他问题。

HTML：

<ul class="list-group ui-sortable" id="todolist">
  <li class="ui-sortable-handle">
    <div class="prettycheckbox">
      <div class="prettycheckbox-success">
        <input class="todocheckbox" type="checkbox" id="checkbox336" aria-label="...">
        <label for="checkbox336">
          <span>I'm a task!</span>
          <a href="#notification-modal" id="notification336" class="notification-button pull-right" data-toggle="modal" data-task-id="336" data-due-date="1111-11-11">
            <span><i class="fa fa-bell-o" aria-hidden="true"></i></span>
          </a>
          <a href="" class="deletebutton pull-right" id="delete336">
            <span><i class="fa fa-times" aria-hidden="true"></i></span>
          </a>
        </label>
