CSS DIV Inline at bottom

Question

I have 3 divisions to put inline at the bottom. I've no idea on how to do that... anybody can help me?

The expected output:

The codes I've tried:

.feature-description
{
  margin-top: 20px;
  padding-left:10%;
  padding-right:10%;
}
.start-up-phase
{
  background-color: #a82327;
  color: #fff;
  padding: 13px 22px  100px;
  text-align: justify;
  width:86%;
  margin-left:auto;
  margin-right:auto;
  min-height:350px;
}
.growth-phase
{
  background-color: #196b8c;
  color: #fff;
  padding: 13px 22px  110px;
  text-align: justify;
  width:86%;
  margin-left:auto;
  margin-right:auto;
  min-height:450px;
}
.expansion-phase
{
  background-color: #53752f;
  color: #fff;
  padding: 13px 22px 200px;
  text-align: justify;
  width:86%;
  margin-left:auto;
  margin-right:auto;
}
.phase-title
{
  border-bottom: 1px solid #fff;
  padding-bottom:10px;
}
.phase-content
{
  padding-top:5px;
}

You can use flexbox with media queries to do this https://jsfiddle.net/2Lzo9vfc/227/

@media(min-width: 1200px) {
    .row.feature-description {
        display: -webkit-flex;
        display: flex;
        -webkit-align-items: flex-end;
        align-items: flex-end;
    }
}
