What is the error in CONTENT'S ARE FLAMMABLE

There should be no apostrophe before the S in 'content's'

The adjectives flammable and inflammable mean exactly the same thing: easily set on fire and capable of burning quickly. Metaphorically speaking, inflammable also can mean easily angered or excited. Of the two terms, the older word for something capable of burning is inflammable, but early in the 20th century the word flammable was coined as a synonym for inflammable. The adjective nonflammable means not easily set on fire.
