title: Bootstrap row equally spaced in within parent
body: <p>I am working in a bootstrap code, where I need to place multiple rows equally spaced within its container.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.myContainer{
      background-color: lightblue;
      height: 200px;
    
    }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"&gt;&lt;/script&gt;
  &lt;script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"&gt;&lt;/script&gt;
  &lt;link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/&gt;
  
  
  &lt;div class="container myContainer"&gt;
    &lt;div class="row"&gt;
      &lt;div class="col-xs-9 col-md-7" style="background-color:red;"&gt;.col-xs-9 .col-md-7&lt;/div&gt;
      &lt;div class="col-xs-3 col-md-5" style="background-color:lavender;"&gt;.col-xs-3 .col-md-5&lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="row"&gt;
      &lt;div class="col-xs-6 col-md-10" style="background-color:lavenderblush;"&gt;.col-xs-6 .col-md-10&lt;/div&gt;
      &lt;div class="col-xs-6 col-md-2" style="background-color:lightgrey;"&gt;.col-xs-6 .col-md-2&lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="row" style="background-color:lightcyan;"&gt;
      &lt;div class="col-xs-6"&gt;.col-xs-6&lt;/div&gt;
      &lt;div class="col-xs-6"&gt;.col-xs-6&lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;
      </code></pre>
  </div>
  </div>
  </p>
  
  <p>Here is a sample html code.
  I want the row div to be equally spaced vertically as the height of the container changes. Each of the row will have multiple columns that will hold actual data field.</p>
  
  <p>You can see in the code snippet that the container itself is 200 pixel high.
  I wan to space the rows equally over the container. spacing should be changing if the container changes its height.</p>
  
  <p>Any suggestion? </p>
