How to align divs and rows with bootstrap

Question

I have trouble aligning nested rows. See picture below. I have 1 row as 9, and 3 rows as 3. 9+3=12 on md and lg screen. In sm screen i would like to have row one as 12 and the 3 other rows under it(4+4+4).

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

This works using Boostrap v4

<div class="container">
 <div class="row">
   <div class="col-md-9 col-sm-12 large">
     <p>

     </p>
   </div>
  <div class="col-md-3 col-sm-3 col-xs-4 small">
   <p>
    Lorem ipsum dolor sit amet, consectetur adipisicing elit. Impedit qui exercitationem placeat doloribus aut id recusandae pariatur. Illum, porro aut ullam? Adipisci tempora fugiat quam quos dolorem, blanditiis dicta magni.
   </p>
  </div>
  <div class="col-md-3 offset-md-9 col-sm-3 col-xs-4 small">
   <p>

  </div>
  <div class="col-md-3 offset-md-9 col-sm-3 col-xs-4 small">

   </p>
  </div>

Answer 4

You just need to get rid of the rows in your second div:

<div class="container">
  <div class="row">
    <div class="col-md-9 col-sm-12">
      <div class="row ">
        <div class="col-md-12 large">
        </div>
      </div>
    </div>
    <div class="col-md-3 col-sm-12">
      <div class="row">
        <div class="col-md-12 col-sm-4 small">
        </div>
        <div class="col-md-12 col-sm-4 small">
        </div>
        <div class="col-md-12 col-sm-4 small">
        </div>
      </div>
    </div>
  </div>
</div>
