javascript - 响应式左侧边栏打开关闭

Question

我有一个关于响应式左侧边栏打开关闭功能的问题。

我创建了这个 DEMO 来自 codepen.io

您可以在演示中看到有一个按钮(单击以显示蓝色 div)。当您单击此按钮时，蓝色 div 将从左侧打开。没关系，但如果您更改浏览器 width < 800px然后是 .left div 将显示。如果您再次单击(单击以显示蓝色 div)之后，蓝色 div 不会打开，同时如果您更改浏览器 width>880px然后你可以看到蓝色的 div 仍然打开，因为你之前点击过它。

我想在浏览器宽度<880px 时实现它，当我单击(单击以显示蓝色 div)时，我想从左侧显示蓝色 div。

我该怎么做才能让任何人在这方面帮助我？

HTML

<div class="test_container">
  <div class="left">
    <div class="left_in">Here is a some text</div>
    <div class="problem-div">
      <div class="proglem-div-in">
      <!--Here is a some menu-->
      </div>
    </div>
  </div>
  <div class="gb" data-id="1" data-state="close">Click To Show Blue Div</div>

问题出在 CSS 上，用这个 CSS 替换媒体查询 css:

@media all and (max-width: 840px) {
  .left {
     z-index: 9999999999999 !important;
  }
  .secret {
    float: left;
    display: block;
  }

  .click_open_close {
    display: block;
  }
}
