Computes to the parent's align-items value.

The effect of this keyword is dependent of the layout mode we are in:

• In absolutely-positioned layouts, the keyword behaves like start on replaced absolutely-positioned boxes, and as stretch on all other absolutely-positioned boxes.
• In static position of absolutely-positioned layouts, the keyword behaves as stretch.
• For flex items, the keyword behaves as stretch.
• For grid items, this keyword leads to a behavior similar to the one of stretch, except for boxes with an aspect ratio or an intrinsic sizes where it behaves like start.
• The property doesn't apply to block-level boxes, and to table cells.

The flex item's margin box is centered within the line on the cross-axis. If the cross-size of the item is larger than the flex container, it will overflow equally in both directions.

Put the item at the start.

Put the item at the end.

Aligns the items to be flush with the edge of the alignment container corresponding to the item's start side in the cross axis.

Aligns the items to be flush with the edge of the alignment container corresponding to the item's end side in the cross axis.

The cross-start margin edge of the flex item is flushed with the cross-start edge of the line.

The cross-end margin edge of the flex item is flushed with the cross-end edge of the line.

Specifies participation in first- or last-baseline alignment: aligns the alignment baseline of the box's first or last baseline set with the corresponding baseline in the shared first or last baseline set of all the boxes in its baseline-sharing group. The fallback alignment for first baseline is start, the one for last baseline is end.

If the combined size of the items along the cross axis is less than the size of the alignment container and the item is auto-sized, its size is increased equally (not proportionally), while still respecting the constraints imposed by max-height/max-width (or equivalent functionality), so that the combined size of all auto-sized items exactly fills the alignment container along the cross axis.

Used alongside an alignment keyword.

The inherit CSS keyword causes the element to take the computed value of the property from its parent element.

The initial CSS keyword applies the initial (or default) value of a property to an element.

The revert CSS keyword reverts the cascaded value of the property from its current value to the value the property would have had if no changes had been made by the current style origin to the current element.

Ref.: https://developer.mozilla.org/en-US/docs/Web/CSS/revert

The revert-layer CSS keyword rolls back the value of a property in a cascade layer to the value of the property in a CSS rule matching the element in a previous cascade layer.

The unset CSS keyword resets a property to its inherited value if the property naturally inherits from its parent, and to its initial value if not.
