1. Understanding Flex Alignment

In Flexbox, alignment refers to the positioning of flex items within a flex container along the cross-axis (perpendicular to the main axis). The align-items property controls the alignment of individual flex items, while the align-content property manages the alignment of multiple lines of flex items within a flex container.

2. The align-items Property

The align-items property defines how flex items are aligned within the flex container along the cross-axis.

Values:

  • flex-start: Aligns items at the start of the cross-axis.
  • flex-end: Aligns items at the end of the cross-axis.
  • center: Centers items along the cross-axis.
  • baseline: Aligns items based on their text baselines.
  • stretch: Default value. Stretches items to fill the container along the cross-axis.

3. The align-content Property

The align-content property determines how lines of flex items are aligned within the flex container when there is extra space along the cross-axis.

Values:

  • flex-start: Aligns lines at the start of the container.
  • flex-end: Aligns lines at the end of the container.
  • center: Centers lines within the container.
  • space-between: Distributes lines evenly with space between them.
  • space-around: Distributes lines evenly with space around them.
  • stretch: Default value. Stretches lines to fill the container.
