HTML, CSS and jQuery: Make a vertical menu with animation

In modern web design, dynamic effects have become one of the important factors to attract users’ attention. one. In the navigation menu of the web page, animation effects can provide users with a better visual experience and operability. This article will introduce how to use HTML, CSS and jQuery to create an animated vertical menu, and provide specific code examples.

1. HTML part

First, we need to use HTML to build the structure of the menu. Add a div element in the body tag to wrap the entire menu. Then, add an unordered list (ul) in that div element as a container for the menu items. Each menu item requires a link (a) element to jump to the corresponding page. Here is a simple HTML code example:

<div class="vertical-menu">
  <ul>
    <li><a href="#">菜单项1</a></li>
    <li><a href="#">菜单项2</a></li>
    <li><a href="#">菜单项3</a></li>
    <li><a href="#">菜单项4</a></li>
  </ul>
</div>

2. CSS section

Next, we need to use CSS to style the menu. First, add basic styles to the menu items, such as background color, text color, and margins. Then, use CSS selectors to style the menu items when you hover over them to achieve the hover effect. Finally, add animation effects to the menu to enhance the user experience.

The following is a simple CSS code example:

.vertical-menu {
  width: 200px;
  background-color: #f1f1f1;
}

.vertical-menu ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
}

.vertical-menu li a {
  display: block;
  color: #000;
  text-decoration: none;
  padding: 8px 16px;
}

.vertical-menu li a:hover {
  background-color: #ddd;
}

.vertical-menu li a.active {
  background-color: #4CAF50;
  color: #fff;
}

.vertical-menu li a.active:hover {
  background-color: #45a049;
}

3. jQuery part

Finally, we use jQuery to animate the menu. We can use the .slideToggle() method to expand or collapse the submenu when the menu item is clicked. In addition, we can also use the .addClass() and .removeClass() methods to add or remove the .active class for the currently selected menu item to change its style.

The following is a simple jQuery code example:

$(document).ready(function() {
  $(".vertical-menu li").click(function() {
    $(this).children("ul").slideToggle("slow");
    $(this).children("a").toggleClass("active");
  });
});

Now, we have completed the creation of a vertical menu with animated effects. When the user clicks on a menu item, the submenu animates to expand or collapse, and the currently selected menu item changes background color. You can further optimize and adjust the code according to your needs to achieve more personalized effects.
