What is CSS Syntax?
A CSS rule-set consists of a selector and a declaration block:
The selector points to the HTML element you want to style.
The declaration block contains one or more declarations separated by semicolons.
Each declaration includes a CSS property name and a value, separated by a colon.
Multiple CSS declarations are separated with semicolons, and declaration blocks are surrounded by curly braces.
Example
In this example all <p> elements will be center-aligned, with a red text color:
p { color: red; text-align: center; }
