CSS Syntax
Learn the basic syntax of CSS and understand how selectors, properties, and values form a CSS rule.
What is CSS Syntax?
CSS syntax is the standard way of writing CSS rules. It tells the browser which HTML element should be styled and what style should be applied.
A basic CSS rule contains a selector followed by one or more declarations.

CSS Syntax
selector {
property: value;
}
This is the basic structure that you will use when writing CSS rules.
Example 1: Basic CSS Rule
Let us create a paragraph and change its text color using CSS.
Code
<!DOCTYPE html>
<html>
<head>
<style>
p {
color: blue;
}
</style>
</head>
<body>
<p>
Learning CSS Syntax
</p>
</body>
</html>
How It Works
- p is the selector.
- color is the property.
- blue is the value.
- The semicolon ; ends the declaration.

Example 2: Multiple Declarations
A selector can contain multiple declarations. Each declaration contains a property and value.
Code
<!DOCTYPE html>
<html>
<head>
<style>
p {
color: green;
font-size: 22px;
text-align: center;
}
</style>
</head>
<body>

How It Works
- color: green; changes the text color.
- font-size: 22px; changes the text size.
- text-align: center; moves the text to the center.

Important CSS Syntax Rules
- The selector identifies the HTML element.
- Curly braces { } contain CSS declarations.
- A property and value are separated by a colon :.
- Each declaration normally ends with a semicolon ;.
- Multiple declarations can be written inside one CSS rule.
CSS syntax follows a simple pattern: Selector → Property → Value. Once this structure is understood, writing basic CSS becomes much easier.
Summary
CSS syntax defines how CSS rules are written. A rule contains a selector and declarations. Each declaration contains a property and a value. Curly braces contain the declarations, while colons and semicolons separate the parts of a rule.
