<Flex flex-display='inline-flex'>
    ...
</Flex>

flex-items

• start - The cross-start margin edges of the flex items are flushed with the cross-start edge of the line
• end - The cross-end margin edges of the flex items are flushed with the cross-end edge of the line
• center - The flex items' margin boxes are centered within the line on the cross-axis
• baseline - All flex items are aligned such that their flex container baselines align
• stretch - Flex items are stretched such that the cross-size of the item's margin box is the same as the line while respecting width and height constraints

<Flex flex-items='center'>
    ...
</Flex>

flex-content

Advanced props

1. flex-content-align
2. flex-content-justify

Multi values (set value separated by a space)

• flex-content="{1} {2}"

List of values

• start - Lines are packed toward the start of the flex container
• end - Lines are packed toward the end of the flex container
• center - Lines are packed toward the center of the flex container
• between - Lines are evenly distributed in the flex container. If the leftover free-space is negative or there is only a single flex line in the flex container, this value is identical to flex-start
• around - Lines are evenly distributed in the flex container, with half-size spaces on either end
• stretch - Lines stretch to take up the remaining space
