如何脱掉y溢出？

Question

我正在尝试构建一个垂直制表符系统。我还有几个问题，但我遇到问题而没有溢出y位置。

我相信我对内容部分的表现不佳。

<button class="button">A</button>
<button class="button">B</button>
<button class="button">C</button>
<button class="button">D</button>
<button class="button">E</button>
<button class="button">F</button>
<button class="button">G</button>
<button class="button">H</button>
<button class="button">I</button>
<button class="button">J</button>
<button class="button">K</button>
<button class="button">L</button>
<button class="button">M</button>

＆＃13;

＆＃13;

     <div class="content">
<h3 class="heading">Tab 4 Content</h3>
<p class="description">Lorem cumque.</p>

＆＃13;

// ----------------- Variables

wrapper = $(".tabs");
tabs = wrapper.find(".nav-tab");
tabToggle = wrapper.find(".tab-toggle");

// ----------------- Functions

function openTab() {
  var content = $(this).parent().next(".content"),
    activeItems = wrapper.find(".active");

  if (!$(this).hasClass('active')) {
    $(this).add(content).add(activeItems).toggleClass('active');
    wrapper.css('min-height', content.outerHeight());
  }
};

// ----------------- Interactions

tabToggle.on('click', openTab);

// ----------------- Constructor functions

$(window).load(function() {
  tabToggle.first().trigger('click');
});
