O3. Drop viewport units IE 8 does not support (TOC v2)
Closed, ResolvedPublic

Description

We are using vh, a new unit suffix (meaning percentage of viewport height), a new CSS feature that IE 8 does not support. I haven't tested yet, but this almost definitely causes major UI breakage in IE 8.

See http://caniuse.com/#search=vh .
