How to align content of a div to the bottom

Answer 1

All these answers and none worked for me... I'm no flexbox expert, but this was reasonably easy to figure out, it is simple and easy to understand and use. To separate something from the rest of the content, insert an empty div and let it grow to fill the space.

.myContainer {
  display: flex;
  height: 250px;
  flex-flow: column;
}

.filler {
  flex: 1 1;
}

  
Top
  

  
Bottom

This reacts as expected when the bottom content is not fixed sized also when the container is not fixed sized.
