Flex - Align Elements Horizontally In The Remaining Space

Im learning Flex as I go along. I think the code will do a better job of explaing the issue.


I have two elements (

) in a container which need to be moved to the empty space alongside the numbers container. I think flex can do this, can it?


You need to do a few things:

  1. Change the flex-direction property of the .btnContainer element to row.
  2. Change the justify-content property of the .btnContainer element to flex-start.
  3. Reduce the width of the .numberParent element by 12px.
