I thought the ID attribute was “unique”—that you could only use it once per page. ??
The attribute isn’t unique, the attribute can be used multiple times. But each name of id element should be unique, so this is fine:
<div id="one"></div> <div id="two"></div>
<div id="one"></div> <div id="one"></div>
although browser do allow the latter one as well, its not good practice.
Does codecademy hav a course in WordPress too? More advanced
Nope, no wordpress course
but wordpress is simple, its drag and drop which means you don’t even have to know html & css.
