The syntax is divided in selector, property and value. The selector could be every HTML-element, paragraph, heading or the body-tag. The property is responsible for the style and in combination with its value, the actual change will be achieved. To refer from the property to the value it is necessary to add a colon after the property. Of course it is possible to change different properties at once. To do so, you just have to end the declaration(property + value) with a semicolon and start again with a new declaration.
