The Rule: Selector and Declaration

Each rule has two parts - the selector and the declaration.


  h1 {color:red}

Left side of the rule: the selector.: The part of the rule that selects the parts of the document to which the styles should be applied
Right side of the rule: the declaration.: A combination of a CSS property and a property value. Declarations always begin and end with curly braces.
