@Malvoz Ah, nice, thanks! Then this can be closed. Tried to find that, but didn't since I only searched for two value. Curious why MDN chose "Multi-keyword"…?

@Schweinepriester I was specifically searching CanIUse for MDN data using the display keyword and unticking the Caniuse checkbox. 😋

It's multi-keyword as opposed to "two-value" because it isn't restricted to only 2 display values.
The spec shows that the display: block flow list-item declaration can be used to generate a block box with additional marker box for example. I.e. one of each <display-outside>, <display-inside> and <display-listitem>.
