In CSS, an ID rule (or ID style rule, or ID style) is a style rule which selects zero or one HTML element based on the element's ID attribute.
Description
An ID rule must apply exactly one HTML element on a page (or no HTML element at all).
No two HTML elements on a given web page may have the same value for their ID attributes.
Example
ID style rule:
#example { color: red}
Element affected by rule:
<div id="example">...</div>
