Block vs. Inline
Block elements stack vertically:
<div> block element
<p> block element
<h3> block element
Inline elements sit side by side:
This paragraph has a link and some bold text and emphasis and a span all flowing inline.
Toggle display to see the switch:
Item 1
Item 2
Item 3
Current: display: inline
