CSS Syntax

A CSS rule set contains a selector and a declaration block.


CSS Selector Example


  • 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: All <p> elements will be center-aligned, with a red text color:

p {  
color: red;
text-align: center;


  • p is a selector in CSS (it points to the HTML element you want to style: <p>).
  • color is a property, and red is the property value
  • text-align is a property, and center is the property value
