Properties may probably be replaced with a shorthand

Reports a set of longhand CSS properties and suggests replacing an incomplete set of longhand CSS properties with a shorthand form, which is however not 100% equivalent in this case.

For example, 2 properties: outline-color and outline-style may be replaced with a single outline. Such replacement is not 100% equivalent because shorthands reset all omitted sub-values to their initial states. In this example, switching to the outline shorthand means that outline-width is also set to its initial value, which is medium.

This inspection doesn't handle full sets of longhand properties (when switching to shorthand is 100% safe). For such cases see the 'Properties may be safely replaced with a shorthand' inspection instead.
