Thanks! And a question.

This is super stuff for HTML/CSS for C++ people like myself. Congratulations on making it so simple. Thank you.

Question: How does one nest these styles? For example, stack 3 rows of buttons, each of which is centered in the page? Thanks again for listening.

	<div class="flex vstack">
		<div class="flex hstack">
			<div>
				<button onclick="callit('callout1','data1')">Click callout1 </button>
			</div>
			<div>
				<button onclick="callit('callout2','data2')">Click callout2 </button>
			</div>
			<div>
				<button onclick="callit('callout3','data3')">Click callout3 </button>
			</div>
		</div>
