2. Allowed CSS Properties

There are some values, which listed in the allowed values, but they are more like representing what kind of value can be used. So for example there are the place in values like font-size: inherit, this value can be used as such. However, e.g. length is a representation of numeric value combined with length metric such as 12cm. So in practice it looks the following: font-size: 12cm and NOT font-size: length Here we list the values with examples, which are representation of some metric rather than in place usable values.
