Html 为什么我的主容器太宽？只有一个9列和3列

我正在创建一个页面，左边是col-3，右边是col-9，col-3和jumbotron中有导航，col-9中有文本，但由于某些原因，页面显示得太宽，需要滚动条来导航页面的整个宽度

除了谷歌搜索没有产生任何效果之外，我还没有做过很多尝试

    <div class = "row">
      <div class = "col-sm-3">

      </div><!--closing of left column-->

  <div class = "col-sm-9">
    <div class = "container">
      <div class = "row">
        <div class = "col-sm-12 text-center">
          <div class = "row text-center">
            <h1>Oregon Tulip Festival</h1>
          </div>
  <div class = "jumbotron img-responsive">
  <div class = "container">
  <div class = "row">
  <div class = "col-sm-12">
  <p class = "jumbo">Sunset at the Tulip Festival</p>
        </div>
    </div>
          </div>
        </div><!--closing of jumbotron-->
<hr>
<h2>Tulip festival | Experience Oregon's finest tulip arrangement</h2>
</div>
    </div><!--closing of small container-->

  </div><!--closing of right column-->
</div>
</div><!--closing of large container-->
</div>```

I have all the divs closed off, so I don't really know how to eliminate the unnecessary width. Could it possibly be my jumbotron?

我已经关闭了所有的div，所以我真的不知道如何消除不必要的宽度。那可能是我的巨无霸吗？

此布局不需要多次使用容器，请尝试下面的HTML结构。我希望这个结构能对你有所帮助

<div class = "container">
<div class = "row">
    <div class = "col-sm-3">
    </div>
    <div class = "col-sm-9">
        <div class = "row">
            <div class = "col-sm-12 text-center">
                <div class = "row text-center">
                    <h1>Oregon Tulip Festival</h1>
                </div>
                <div class = "jumbotron img-responsive">
                    <div class = "row">
                        <div class = "col-sm-12">
                            <p class = "jumbo">Sunset at the Tulip Festival</p>
                        </div>
                    </div>
                </div>
                <hr>
                <h2>Tulip festival | Experience Oregon's finest tulip arrangement</h2>
            </div>
        </div>
    </div>
</div>
