宽度 100% 未使用全屏

Question

我已经构建了一个修改后的选项卡图表。当您单击左侧的选项卡时，它们会切换右侧的内容。唯一的问题是右侧的主要内容 div，即使宽度为 100%，也只能穿过屏幕的三分之一左右。任何想法为什么？

* {
  padding: 0;
  margin: 0;
}
#container {
  display: block;
  height: 100%;
  width: 100%;

  width: 100%;
  background-color: #FAFAFA;
  border-bottom: 1px solid #d9d9d9;
  display: block;
  position: relative;
  z-index: 2;
}
#topBar2 {

  width: 100%;
