This time I will bring you CSS to implement a first-level navigation bar. What are the precautions for implementing a first-level navigation bar with CSS? The following is a practical case, let’s take a look.

Step one: Introduce the css style sheet, create a new layer with the id nav, and use the

, tags to create the complete effect.

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title></title>
        <link rel="stylesheet" type="text/css" href="css/yiji.css"/>
    </head>
    <body>
        <p id="nav">
            <ul>
                <li><a href="">首页</a></li>
                
                <li><a href="">首页</a></li>
                
                <li><a href="">首页</a></li>
                
                <li><a href="">首页</a></li>
                
                <li><a href="">首页</a></li>
            </ul>
        </p>
    </body>
</html>

The second step is to set the CSS style:

1. Set the attributes of nav

#nav{
    width: 500px;
    height: 50px;
    border: 1px solid red;
}

The display effect is as follows:

##2. Clear the dot in front of the

tag
#nav ul{ list-style: none; }

3. Set the properties of the tag contained under

#nav ul li a{ width: 98px; height: 50px; float: left; border: 1px solid red; text-align: center; line-height: 50px; text-decoration: none; }

4 .Set the mouse over effect

#nav ul li a:hover{
    background-color: #ABCDEF;
}

Final effect:

Complete HTML code part ：

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title></title>
        <link rel="stylesheet" type="text/css" href="css/yiji.css"/>
    </head>
    <body>
        <p id="nav">
            <ul>
                <li><a href="">首页</a></li>
                 
                <li><a href="">首页</a></li>
                 
                <li><a href="">首页</a></li>
                 
                <li><a href="">首页</a></li>
                 
                <li><a href="">首页</a></li>
            </ul>
        </p>
    </body>
</html>

Complete the CSS style code part:

*{
    margin: 0;
    padding: 0;
}
#nav{
    width: 500px;
    height: 50px;
    border: 1px solid red;
    margin: 30px;
}
#nav ul{
    list-style: none;
}
#nav ul li a{
    width: 98px;
    height: 50px;
    float: left;
    border: 1px solid red;
    text-align: center;
    line-height: 50px;
    text-decoration: none;
}
#nav ul li a:hover{
    background-color: #ABCDEF;
}
