Recently, CSS has undergone a change where the display property is now split into an inner display and outer display.
With the legacy value of display: inline-block, it raises the question of what the newer equivalent should be.
One might assume that the updated version could be display: inline flow, but a quote mentioned throws this off:
Note: Browsers supporting the two-value syntax will default to
flowfor the inner value when only the outer value is specified, as seen withdisplay: blockordisplay: inline. This ensures expected behavior regarding layout. For instance, setting an element to block would infer that its children participate in block and inline normal flow layout.
This indicates that display: inline functions similarly to display: inline flow. Since display: inline differs from display: inline-block, the latter cannot simply be replaced by display: inline flow.
The question remains: what should the new value be? Despite thorough research on the provided links and other online sources, no alternative values have emerged.
