Some properties defined here don't exist

[simon-paris]

The following properties don't exist, they were probably part of an early draft of css that has since changed.

• font-effect
• font-emphasize (text-emphasis exists)
• font-emphasize-position
• font-emphasize-style
• text-outline (text-shadow and -webkit-text-stroke exists)
• text-overflow-ellipsis
• text-overflow-mode
• color-profile (an at-rule with the same name exists)
• font-smooth (This one was implemented as -webkit/moz-font-smoothing. The MDN page says it's called font-smooth but no browser supports it by that name. Caniuse lists all the names that actually work.)

I found some references to some of these here: https://chenhuijing.com/blog/tracing-the-history-of-css-fonts/#%F0%9F%A6%8A
