Same equation, different display

MathML equations are displayed differently depending on if they are inline or block.

Block equations are sometimes referred to as display equations in authoring tools.

If an equation is displayed as inline, then it is styled to fit within the available space between lines of text within a paragraph. Inline equations are represented in MathML as <math display="inline"> or just <math>.

If the equation is displayed as block, then it can have more space on the top and bottom, since it's not tied to any line height.  Block equations are represented in MathML as <math display="block">.

Display style	Description	Example
Inline	The equation is inline, or adjacent, with a paragraph. Inline equations are represented in MathML as <math display="inline"> or just <math>.
Block	The equation is the only item in a paragraph. Block equations are represented in MathML as <math display="block">.

Adjusting the spacing in equations depends on whether the equation is displayed as inline or block.

Typefi's Adjust Equation event script automatically adjusts the spacing for you.
