That is your jumbotron code from your post -- something bad has happened there. Why is there a row and column in there and what happened to

        <h1>Find a place to stay.</h1>
        <p>Rent from people in over 34,000 cities and 192 countries.</p>

Sort that out first and then we can look at the rest.

Here is the overall plan that you are aiming for:

<!DOCTYPE html>

  <head>
    ... links in here

  <body>

    <div class="nav">
      <div class="container">
      ... your nav code goes in here
      </div>
    </div>

    <div class="jumbotron">
      <div class="container">
      ... your jumbotron code goes in here
      </div>
    </div>
    
    <div class="neighborhood-guides">
      <div class="container">
      ... your neighborhood-guides code goes in here
      </div>

    <div class="learn-more">
