[SOLVED] Color not lengthening, block. How to fix?

Question

css

Again I ask a question.
The problem is that the block is not extended.
The color should fill the bottom but it doesn't. (Sorry, I don't know how to put it).

<div class="container main">
  <row>

   <div class="col-sm-9 content">
    <div class="block-name">
      Последняя новость
    </div>
    <div class="short-story">
      <div class="col-sm-4">
        <img src="images/wm_cover.jpg" class="img-responsive">
      </div>
      <div class="col-sm-8">
        Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
        tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam,
        quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo
        consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse

      </div>
    </div>
  </div>

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

  </row>
</div>

.main {
  margin-top: 60px;
  margin-bottom: 60px;
}
.block-name {
  background: #323232;
  padding: 15px;
  color: #fff;
  text-transform: uppercase;
  font-weight: bold;
}
div.short-story {
  background: #eaeaea;
  padding: 15px;
  border: 1px solid #dfdfdf;
  height: 100%
}

Answer 1

an element with class col-**-** must be inside an element with class .row
