css div id used only once per page

Question

In using CSS is it best practice to use a div id only once per page. I know each id has to be unique but could be used multiple times. A discussion with my development tea

Answer 1

ID's are Unique Assigments for ONE element on A page.

You can use the "ID=" attribute more than once. You will need to make sure that ID="hi" is only used once as it is supposed to be a unique identifier at the element level.
