  1. Hello guys, I hope I'm in the right section for these kind of problems. I have trouble linking the HTML document with the CSS. I know it's a very dumb problem, and I'm not even a newbie. It's super frustrating because I can't figure out the issue. The document I'm using is for a tutorial about Bootstrap.

From this value a new query is done. So first connection is done. But can I use this connection or should I make a new one?
