Implementation steps of implementing menu navigation bar with shadow effect using pure CSS

The steps to implement the menu navigation bar with shadow effect using pure CSS require specific code examples

In web design, the menu navigation bar is a very common element . By adding a shadow effect to the menu navigation bar, you can not only increase its aesthetics, but also improve the user experience. In this article, we will use pure CSS to implement a menu navigation bar with a shadow effect, and provide specific code examples for reference.

The implementation steps are as follows:

Create HTML structure
First, we need to create a basic HTML structure to accommodate the menu navigation bar. The following is a simple example:

<!DOCTYPE html>
<html>
<head>
  <title>带阴影效果的菜单导航栏</title>
  <link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
  <ul class="menu">
    <li><a href="#">首页</a></li>
    <li><a href="#">关于我们</a></li>
    <li><a href="#">产品</a></li>
    <li><a href="#">联系我们</a></li>
  </ul>
</body>
</html>

Add CSS style
Next, we need to add CSS style to the style sheet file (style.css) to achieve the shadow effect menu navigation bar. Here is the complete CSS code example:

.menu {
  list-style-type: none;
  margin: 0;
  padding: 0;
  background-color: #fff;
  box-shadow: 0px 2px 5px rgba(0, 0, 0, 0.1);
}

.menu li {
  display: inline-block;
  margin-right: 10px;
}

.menu li a {
  display: block;
  padding: 10px;
  text-decoration: none;
  color: #333;
  font-weight: bold;
}

.menu li a:hover {
  background-color: #f5f5f5;
}

.menu li:first-child {
  margin-left: 10px;
}

Parse code

First, we added .menu for the menu navigation bar container class and set some basic styles. We set the list style type to none, removing the default list item style. Next, we applied a shadowed box-shadow effect to the menu navigation bar container. The meanings of the parameters here are: set the shadow to not offset in the horizontal direction (0px), and set the shadow in the vertical direction. The offset is 2 pixels (can be adjusted as needed), the shadow's blur radius is 5 pixels, and the shadow's color is an RGBA value.

Then, we set the style for each li list item. We set the display property to inline-block so that the list items are arranged horizontally. At the same time, we added a margin-right attribute to control the spacing between list items. Here we set it to 10 pixels, you can adjust it as needed.

Next, we set some basic styles for the links of each menu item, such as displaying as block-level elements, padding, font color and weight, etc. We set a background color when the mouse is hovering over the link to improve visualization.

Finally, we use the :first-child pseudo-class selector to set a margin-left attribute for the first list item to avoid conflict with the menu navigation bar Containers are too far apart.

Conclusion
Through the above steps, we successfully implemented a menu navigation bar with a shadow effect. You can make custom style changes as needed to adapt it to your website design. With pure CSS, we can achieve a variety of cool effects without relying on JavaScript. I hope this article is helpful to everyone, thank you for reading!
