VBA object is something like a tool or a thing that has certain functions andproperties, and can contain data.Cell is also an Excel VBA object, but it is also the property of the range object.

Range hashigher hierarchy than cells, and interior has lower hierarchy than Cells, and color haslower hierarchy than Interior, so you can write&ange(-%10%=our&ange@#1/ont1Bold=True&ange (>=our&ange@#1/ont1Itali!=True&ange (>=our&ange@#1/ont1:nderline=TrueThe FontStyle property can actually be used to replace all the properties above toachieve the same formatting efects.
