CSS CSS Basics (2014) Basic Selectors ID Selectors

8,379 Points

ID is being applied to multiple instances on same page.

I gave several P elements the id="primary-content" and they all received the red border. But the video states I can only use 1 id per element, per page.

Shouldn't the border NOT be applied to all instances?

It'll work, browser will let you use multiple ids on the same page, but it's not best practices, and you should avoid doing so. A class would the be appropriate choice here.

Mh, I think they meant that you should not reuse an ID as it doesn't makes sence. If you want to apply something to multiple elements classes are better suited.
