HTML/CSS结构未按预期方式运行

我有一些html代码，我正在尝试获得：

部件包括：

.main wrapper-我需要保持这一点的绝对值，以便里面的元素使用百分比大小。我不想用vh或vw。

.main.-这需要始终是100%的高度和宽度。

.tbar-需要始终在.main 的左侧可见

.side-将切换从左侧滑动，并在打开时按下.bar和.main。

我希望我能正确地解释。

以下是我尝试过但不对的：

<!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

    <title></title>
    <style>
    .main-wrapper {
        position: absolute;
        top: 59px;
        right: 0;
        bottom: 0;
        left: 0px;
        border-left: 3px solid blue;
        background-color: grey;
    }
    .main-wrapper .side {
        width: 300px;
        height: 100%;
        background-color: blueviolet;
    }
    .main-wrapper .tbar {
        position: relative;
        left: 0px;
        height: 100%;
        width: 50px;
        background-color: green;
    }
    .main-wrapper .main {
        width: 100%;
        height: 100%;
        background-color: red;
    }
    </style>
  </head>
  <body>

    <nav class="navbar navbar-dark bg-dark navbar-expand">
        <span class="toggle-leftbar navbar-brand"><button id="togglebtn">Toggle</button></span>
        <a class="sidebar-toggle mr-3" href="#"><i class="fa fa-bars"></i></a>
        <div class="navbar-collapse collapse">
            <ul class="navbar-nav ml-auto">
                <li>Test</li>
            </ul>
        </div>
      </nav>

      <div class="main-wrapper">
        <div class="side">Side Here</div>
        <div class=tbar>TBar</div>
        <div class="main">Main Here</div>
      </div>

    <script>
        $( document ).ready(function() {
           $('.side').toggle();
        });
    </script>

</html>

我如何才能让这些零件满足我的需要？

您也定义了$('.side').toggle();，但当您单击切换按钮时，时间工作为$('.side').toggle();，所以您在内部尝试单击函数时，添加如下代码。。

 $( document ).ready(function() {
        
            $( "#togglebtn" ).click(function() {
              $('.side').toggle();
            });
});

   .main-wrapper {
        position: absolute;
        top: 59px;
        right: 0;
        bottom: 0;
        left: 0px;
        border-left: 3px solid blue;
        background-color: grey;
    }
    .main-wrapper .side {
        width: 300px;
        height: 100%;
        background-color: blueviolet;
    }
    .main-wrapper .tbar {
        position: relative;
        left: 0px;
        height: 100%;
        width: 50px;
        background-color: green;
    }
    .main-wrapper .main {
        width: 100%;
        height: 100%;
        background-color: red;
    }
