Javascript 固定+流体引导模板与非画布侧栏

我发现这段代码用于固定+流体引导模板，带有非画布侧边栏

我的测试表明，它在Chrome和Firefox上运行良好，在Internet Explorer中崩溃，在Windows Safari中，内容列向左移动，留下与下图所示边栏宽度相等的空白

我还没有测试过其他浏览器，但是我对这个想法很感兴趣

我猜IE中的css计算行有问题：

width:calc(100% + 220px);

代码也在这里：

CSS:

HTML

body,html,.row-offcanvas {
  height:100%;
}

body {
  padding-top: 50px;
}

#sidebar {
  width: inherit;
  min-width: 220px;
  max-width: 220px;
  background-color:#f5f5f5;
  float: left;
  height:100%;
  position:relative;
  overflow-y:auto;
  overflow-x:hidden;
}
#main {
  height:100%;
  overflow:auto;
}

/*
 * off Canvas sidebar
 * --------------------------------------------------
 */
@media screen and (max-width: 768px) {
  .row-offcanvas {
    position: relative;
    -webkit-transition: all 0.25s ease-out;
    -moz-transition: all 0.25s ease-out;
    transition: all 0.25s ease-out;
    width:calc(100% + 220px);
  }

  .row-offcanvas-left
  {
    left: -220px;
  }

  .row-offcanvas-left.active {
    left: 0;
  }

  .sidebar-offcanvas {
    position: absolute;
    top: 0;
  }
}
