According to Management Communication, "When you need to emphasize part of your text, do it properly. Back when everyone wrote on typewriters, the only tools for emphasis were capitalization and underlining, but all$-$caps now looks like SHOUTING, and underlining interrupts the descending strokes of letters." Instead, your text suggests using all of the following techniques to emphasize text EXCEPT:

superscripts

size

colors

italics

grayscale

bolding
