The syntax of a style, as you may have gleaned from our previous examples, is fairly straightforward. A style rule is made up of at least three basic parts: a tag selector, which identifies the name of the tag that the style rule affects, followed by a curly brace ({ }) enclosed, semicolon-separated list of one or more style property:value declaration pairs:
tag-selector {property1:value1; property2:value1 value2 value3; ...}
