I figured everything out, except how
to align several buttons horizontally,
the way I can with containers within
a grid.
For my current application the only
advantage of buttons are that the user
can click anywhere on the button and be
redirected, whereas the user has to
click precisely on the linked-word within
a container in order to be redirected.
You can wrap a container block for the button blocks, set the container to display:flex, it gives you the align-items and justify-content options for vertical and horizontal alignment.
