CSS Syntax
A CSS rule consists of a selector and a declaration block.
CSS Syntax
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;
}
