I can't seem to find the <h2> element in the index.html file, but, is a css style. Is this an error? or I'm I missing something.
The <h2/> might show up later in the course, and if it doesn't, well then welcome to real world CSS. I've done that course and found no errors in it, just keep coding away and don't sweat stuff like that. If the code causes your CPU to catch fire or something then start to be worried.
