You can now use the align-content property from CSS Box Alignment on block and table layouts. This will allow block direction alignment without needing to create a flex or grid layout.

The once impossible task of centering an item vertically was made easier by flexbox and grid, along with the align-content property. However, it did involve creating a flex or grid layout for no other reason than to do this alignment. The property was specified for block layout, and in the past few months all three major engines have shipped the feature.

With align-content available for block layout, you can achieve vertical alignment without needing to create a flex or grid layout for the property to work. No additional properties are needed as the item remains a block item, the only change is to the alignment.
