Short answer:
No. Only px
(default if no unit is specified) and %
are supported.
Long answer:
While it is possible to force a specific height/width for individual panels by using the panel’s style
property (e.g. style: "height: 15em !important;"
), I would not suggest to use it, because the height/width of other panels is still calculated by the original size
property.
If you want to do it that way, be prepared that you will have to specify all height/width values yourself for all panels and resizing will not work – at which point there’s probably no longer a benefit of using the w2layout over designing something with flex boxes yourself.
