What is it?
CSS is used to render information to a device. These devices exist in the real world and have dimensions and capabilities that are measurable. So, CSS provides a way for document content to explicitly specify how it will be mapped to a physical device. If a property value contains an illegal unit measure, the entire style rule should be ignored.
