Styling Navigation bar with logo and button-CodePudding

I have been trying for hours to style my navigation bar(which is horizontal at the top of the screen) so that my logo will show at left , menu on the center and the username with the logout button at right(all of them horizontally).I tried float ,position display, but nothing seems to work as i want.Instead the result is all the elements(logo,menu,username,logout button) to appear in the center.Any help would be appreciated.

HTML code

 <header>   
     <div >
   <nav >
    <div >
   <img src="images/logo.png">
    </div>
    <ul >
      <li ><a href="index.php" >Main</a></li>
      <li ><a href="main.php" >Songs</a></li>
      <li ><a href="ratings.php" >Ratings</a></li>
    </ul>   
    
     <section id="login">
                <a href="registration/logout.php" >Logout</a>
                <h1>User: <?php   echo $user_data['user_name']; ?></h1>
                </section>  
  </nav>     
    </header>

CodePudding user response：

Here is the result what I fixed, please check and let me know. You need to change justify-content: space-between instead center to the menu and add align-items: center and align-items: center to the #login. Added the fixed css code. Hope it is helpful~
