The navigation bar is very important in web design, it can help users quickly find the content they want and improve user experience. Therefore, how to implement a beautiful and easy-to-use navigation bar is a skill that every front-end engineer should master.

In this article, we will introduce how to use CSS to implement a simple navigation bar, including setting the style, layout, interactive effects, etc. of the navigation bar. By reading this article, you will learn how to use some basic properties and techniques of CSS to implement a navigation bar.

Preparation

Before we start writing code, we need to prepare some basic HTML and CSS knowledge so that we can better understand and implement the navigation bar. If you are not familiar with HTML and CSS, you can refer to the following articles:

Implementing Navigation Bar

Below we will introduce how to use CSS to implement a simple horizontal navigation bar.

Step One: HTML Structure

First, we need to create a basic HTML structure to accommodate the navigation bar. In HTML, we can use unordered lists (

) and list items (
• ) to implement navigation bars.

  <nav>
    <ul>
      <li><a href="#">首页</a></li>
      <li><a href="#">产品</a></li>
      <li><a href="#">关于我们</a></li>
      <li><a href="#">联系我们</a></li>
    </ul>
  </nav>

  In the above code, we use a

  tag to represent the navigation bar, and nest a

  tag as the container of the navigation bar. At the same time, we also added four list items (
  • ), each list item contains a link ().

    Step 2: Basic Style

    Next, we need to add some basic styles to the navigation bar, including setting the background color, text color, font size, etc. The code is as follows:

    nav {
      background: #333;
      color: #fff;
    }
    
    nav ul {
      list-style-type: none;
      margin: 0;
      padding: 0;
    }
    
    nav li {
      display: inline-block;
    }
    
    nav a {
      display: block;
      padding: 10px 20px;
      color: #fff;
      text-decoration: none;
    }
    
    nav a:hover {
      background-color: #555;
    }

    In the above code, we set the styles of the navigation bar, navigation bar container, list item, and link respectively. The link will change the background color when hovering.

    Step 3: Implement the layout

    Now that we have completed the basic style of the navigation bar, we need to implement the layout of the navigation bar. We can use the CSS float property to achieve horizontal layout. The code is as follows:

    nav ul {
      list-style-type: none;
      margin: 0;
      padding: 0;
      text-align: center;
    }
    
    nav li {
      display: inline-block;
      float: left;
    }
    
    nav a {
      display: block;
      padding: 10px 20px;
      color: #fff;
      text-decoration: none;
    }
    
    nav a:hover {
      background-color: #555;
    }

    In the above code, we set the navigation bar container to be centered and set the display property of the list items to inline-block so that they can be arranged horizontally. Also use the float: left attribute to achieve better layout effects.

    Step 4: Interaction effects

    The last step is to add some mouse interaction effects to the navigation bar to enhance the user experience. We can use the :hover pseudo-class to achieve the effect of the link when the mouse hovers. The code is as follows:

    nav a:hover {
      background-color: #555;
    }

    In the above code, we added the :hover pseudo-class for the link. When the mouse hovers over the link , the background color will change to gray.
