@MojammelW - the way that I usually use it for CodePen projects is to run the project in the debug view, right click, and "View Page Source". Copy and paste that into the validator.w3.org "Validate by Direct Input" tab, then run the "Check" - it will dump a bunch of errors if you have them.
But you don't need it for this navbar problem - just add that JS, and re-run your page, it should work. It did for me.
wellclass doesn't exist in Bootstrap 4, which is the default in codepen. To use Bootstrap 3 (which has the Well class), replace your link to bootstrap in your codepen settings with: https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css

hi!! guys quick question. im in 170 on my fcc tutorial. can someone explain this to me.
var myArray = [["John", 23], ["cat", 2]];
// Only change code below this line.
var removedFromMyArray = myArray.pop();
on myArry.pop() i tried to put a parameter "2" or any number inside the .pop function and its still correct.
