CSS Syntax
A CSS rule syntax consists of three components: a selector, a property, and a value for the property. The selector refers to the HTML element in which the CSS style is to be used. Semicolons are used to separate the CSS properties.
Syntax:
selector
{
property: value;
}
Example:
h1
{
color: aqua;
}
Explained the example
<h1>
: h1 is the selector.color
: Color is the property.aqua
: Aqua is the property value

CSS declarations consist of a property name and value, separated by a colon (:) and surrounded by curly braces ({ }).
