Custom CSS File wont work on second Page
i created a custom Theme in WordPress and everything is working fine and the CSS is loading to my index.php. So now i copy-pasted the index.php and renamed it, then i went to the indexCopy site and the CSS wont load. In the Code, everything is the sam, except the fileName. When i go back to my index.php, the css IS working. Do you need Code examples for this issue?
What am i doing wrong ?
