What is CSS ID?

An ID in CSS is identified by the octothorpe symbol (#). An ID in CSS references the ID attribute in HTML and they should have the same name. For example lets say I have the following code in my HTML: <small id="copyright">Copyright ©2015 — David Trower. All Rights Reserved.</small> Notice the id="copyright" on the <small> element? That is the ID. In CSS, if I want to stylize this element by referencing that ID I would use the following CSS code: #copyright { color: #9CBDDE; } Notice how what follows the octothorpe (#) symbol in the CSS code is the same as the value of the ID attribute in HTML (both are the word copyright). An ID is to be a unique identifier within a document. It should appear once, and only once, within a single document.
