Troubleshooting HTML/CSS and JavaScript Issues with Dropdown Menus

I'm having trouble getting my dropdown menu to work properly and I can't figure out why. The JavaScript code should toggle a class that hides the language options and slides up the other tabs like "Contact". However, when I click the button, nothing happens at all. The class "dp-click" is supposed to be toggled to show or hide the menu, while the class "dp-contents" controls the visibility of the languages when the "dp-click" class is clicked. Here's the HTML code:

<html>

    <head>
        <link href="Style.css" type="text/css" rel="stylesheet">
        <title>Enforcext</title>
    </head>

    <div class="nav">
        <div class="container">
            <img src="http://www.destinygamewiki.com/images/7/72/Enforcer_medal1.png" width="50px">
            <ul class="links">
                <li style="margin: 5px; margin-left: 15px;"><a href="Index.html">Home</a></li>
                <div class="lt">
                    <div class="dp-click">
                        <li style="margin: 5px; margin-left: 15px" class="dp-click"><a href="#" class="dp-click">Languages</a></li>
                    </div>
                </div>
            </ul>
            <div class="lt">
                <ul class="dp-contents links">
                    <li style="margin: 5px; margin-left: 25px"><a href="PHP.php">PHP</a></li>
                    <li style="margin: 5px; margin-left: 25px"><a href="HTML.html">HTML</a></li>
                    <li style="margin: 5px; margin-left: 25px"><a href="CSS.html">CSS</a></li>
                    <li style="margin: 5px; margin-left: 25px"><a href="Javascript.html">JavaScript</a></li>
                </ul>
            </div class="lt">
            <ul class="links">
                <li style="margin: 5px; margin-left: 15px;"><a href="Contact.php">Contact</a></li>
            </ul>
        </div>
    </div>

    <body>


    </body>
    <script src="Javascript.js"></script>

</html>

CSS:

.nav {
  border: 1px black solid;
  background-image: url(Texture2.jpeg);
  width: 10%;
  height: 100%;
}
.links{
  display: inline;
  text-decoration: none;
}
.links a{
  text-decoration: none;
  display: inline;
  color: yellow;
}
.links a:hover{
  font-family: Impact;
}
.dp-contents{
  height: 0px;
  opacity: 0%;
  color: white;
}
.dp-show{
  color: purple;
  font-size: 20px;
}

JS:

var main = function(){
    $('.dp-click').click(function(){
        $('.dp-contents').toggle();
    });
}
$(document).ready(main);

Answer №1

To begin, make sure to place your div.nav tag within the body element.

Next, check for any coding errors such as:

<li style="margin: 5px; margin-left: 15px;"><a href="Index.html">Home</li>

In this line, remember to include </a> before </li>.

Another mistake can be found here:

</div class="lt">

This is incorrect. Make sure to add </div> and remove the slash from the beginning of the line.

Answer №2

If you are utilizing jQuery, be sure to include the external library by linking it like this: jQuery.

It appears from your code that you have not included the link.

Additionally, make sure to enclose all of your content within the body tag.
