ID selectors are used to identify and apply styling to a single specific HTML element. ID selectors are defined within the HTML page by inserting an ID in the HTML element.
Example:

<h1 id="id-selector">Lorem Ipsum</h1>

ID selectors are defined within the CSS page by calling a ‘#’ followed by the name of the ID.
Example:

#id-selector {
font-family: Arial;
font-size: 20;
}

ID selectors are unique and can only be applied to a single element.
