Javascript 响应性左侧边栏打开关闭

我有一个关于响应式左侧边栏开-关功能的问题

我从codepen.io创建了这个

您可以在演示中看到有一个按钮（单击以显示蓝色div）。单击此按钮时，蓝色div将从左侧打开。可以，但如果更改浏览器

宽度<800px

，则将显示

.left

div。之后，如果再次单击（单击以显示蓝色div）蓝色div未打开，同时如果更改浏览器

width>880px

，则您可以看到蓝色div仍然打开，因为您以前单击过它

我想在浏览器宽度出现CSS问题时使用此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;
  }
}

---

你需要这样做。试着停止用媒体查询隐藏它。@sagar为什么？如果我把它隐藏起来，那我该怎么做才能做出响应。试着用jquery和window resize事件来做。我建议这样做是因为它降低了复杂性$（窗口）。调整大小（函数（）{…}）@萨加尔：是的，你是对的。我以前仍然尝试过，但是

$（window）.resize（function（）{…}）无法解决此问题。感谢回复，但左侧需要执行
左侧：-60%当浏览器
