CSS Syntax

❮ Previous Next ❯

A CSS rule consists of a selector and a declaration block.

CSS Syntax

CSS selector

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;
}
Try it Yourself »

Example Explained

  • 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

You will learn much more about CSS selectors and CSS properties in the next chapters!
