Answer 1

You had some typos and also targeting the wrong ul.

body {
  font-family: 'Lucida Grande', Helvetica, Arial, sans-serif;
  padding: 20px 50px 150px;
  font-size: 13px;
  text-align: center;
  background: #666;
}

.navbar a {
  text-decoration: none;
  color: #FF0004
}

.navbar ul {
  text-align: left;
  display: inline;
  margin: 0px;
  padding: 15px 4px 17px 0;
  list-style: none;
  -webkit-box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
  -moz-box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
  box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
}

.navbar ul li {
  font: bold 12px/18px sans-serif;
  display: inline-block;
  margin-right: -4px;
  position: relative;
  /*position typo */
  padding: 15px 20px;
  background: #fff;
  cursor: pointer;
  -webkit-transition: all 0.2s;
  -moz-transition: all 0.2s;
  -ms-transition: all 0.2s;
  -o-transition: all 0.2s;
  transition: all 0.2s;
}

.navbar ul li:hover {
  background: #555;
  color: #FFF;
}

.navbar ul li ul {
  padding: 0;
  position: absolute;
  /*position typo */
  top: 48px;
  left: 0;
  width: 150px;
  visibility: hidden;
  -webkit-transition: opacity 0.2s;
  -moz-transition: opacity 0.2s;
  -o-transition: opacity 0.2s;
  -transition: opacity 0.2s;
}

.navbar ul li ul li {
  background: #555;
  display: block;
  color: #FFF;
  text-shadow: 0 -01px 0 #000;
}

.navbar li ul li:hover {
  background: #666;
}


/* i refactored this selector */

.navbar ul li:hover ul {
  display: block;
  opacity: 1;
  visibility: visible;
}

<div class="navbar">
  <ul>
    <li><a href="home.html">Home</a></li>
    <li><a href="recepten.html">Recepten</a>
