To invoke the CSS provided, an ID selector is used. In CSS, the ID selector is used to style the element with the specific id attribute.
* CSS ID Selector: The syntax for the ID selector is #id, where id is the id attribute value of the HTML element.
* Usage Example:
#black {
color: black;
}
This CSS rule will apply the color: black; style to the element with id="black".
* Example in HTML:
<div id="black">This text will be black.</div>
