Seems like an odd request in 1993. Sure, Prodigy had visual impact, but it was pretty hard to read. HTML's starkness seems in part due to the fact that styling options were limited by the technology and the ones that existed were easily abused.
Writing long sentences as headers (<h1>) or all-caps (caps-lock) were styling options at the time... and often misunderstood and abused.
