/* Create two columns/boxes that floats next to each other */
nav {
    float: left;
    width: 30%;
    background: #ccc;
    padding: 20px;
    padding-bottom: ;
}

/* Style the list inside the menu */
nav ul {
    list-style-type: none;
    padding: 0;

nav ul li{
    border-left: 6px solid blue;

我在CSS中没有添加height: 100%;导航，请尝试以下操作：

/* Create two columns/boxes that floats next to each other */
nav {
    float: left;
    width: 30%;
    height: 100%;
    background: #ccc;
    padding: 20px;
    padding-bottom: ;
}

/* Style the list inside the menu */
nav ul {
    list-style-type: none;
    padding: 0;
    line-height: 250%;
}
nav ul li{
    border-left: 6px solid blue;
    background-color: #66c2ff; 
    border-collapse: separate;
    border-spacing: 30%;
}

nav ul li a{
    padding-left: 12px;
    font-size: 25px;
    color: black;
    text-decoration: none;
}

<nav>
    <ul>
        <li><a href="#">NSS IIT Bombay Home</a></li>
        <li><a href="#">NOCS and NSS</a></li>
        <li><a href="#">Letter from OC</a></li>
        <li><a href="#">Registration</a></li>
        <li><a href="#">Why NSS?</a></li>
        <li><a href="#">Some Experiences</a></li>
    </ul>
  </nav>
