Fallback alignment

In CSS Box Alignment, a fallback alignment is specified in order to deal with cases where the requested alignment cannot be fulfilled. For example, if you specify justify-content: space-between there must be more than one {{Glossary("alignment subject")}}. If there is not, the fallback alignment is used. This is specified per alignment method, as detailed below.

• First baseline
  • : start
• Last baseline
  • : safe end
• Baseline
  • : start
• Space-between
  • : flex-start (start)
• Space-around
  • : center
• Space-evenly
  • : center
• Stretch
  • : flex-start (start)
