选项卡式界面如​​何编辑

Question

下面的代码是一个标签式界面，在按下标签时会显示下面的文字。 我阅读了大量文章，他们似乎都建议使用UL或div id=。我无法找到这个代码的任何内容，它是Web模板的一部分。

默认情况下，第一个标签上会显示文字？

<div class="inner_tabarea">
<div class="inner_menu">
  <div align="center">
  <a href="#" class="innermenu_hover">Events</a>
  <a href="#" class="innermenu">Bookings</a>
  <a href="#" class="innermenu">Meeting</a> 
  <a href="#tab4" class="innermenu">Subscribe</a> </div>
</div>
<div class="tab_text">
  <p class="tab_head">ON WEDNESDAY 16TH OCTOBER 2013</p>
  <p><span class="tab_head1">Canary Evening</span><br />

  folklore music.Traditional paella and Sangria will be served for our guest
