Site is not hosed on codepen, but rather nitrious.io it helps as its a real vps server which include enviroemnt setup folder etc ,i feel thats important to learn too.
One thing that remains confusing is the number of div open and close tags, it becomes very hard to know which belongs to which, i understand i can do tab spacing better, but in a big project i guess the best solution is to code in SNIPPETS and keep each div that does some functionality in a separate html file and then use a build tool to combine in to one… is this the best way?? i dont know why my footer tag at the panel is not showing in the correct place.
