Aligning Block Content

You can align all the block's content, such as text and images, by clicking on the Alignment button in the block's toolbar.

You can also do this through the Content Alignment option found in the Layout tab of the Inspector.

The above methods change the alignment of all the blocks' content at the same time. 

If you want to change the alignment of the individual block elements, click the individual blocks and adjust the alignment through the toolbar or Inspector.
