How to push down the <div> below when dropdown menu buttons are appearing?

I am working on that website just to learn HTML and CSS, without JS first. So that's why I look for a solution without JS here.

When the page is smaller than 1081px in width the menu buttons on the top become a burger menu. If clicked the menu buttons pop up below the nav bar - but - unfortunately the buttons are right on the top of the boxes below, which I want to push down when the burger menu is clicked on. Can someone give me a hint on how to do that? I can't find any solution online without jscript.

HTML:

    <!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width-device-width, initial-scale=1.0">
        <link rel="stylesheet" type="text/css" href="style.css">
        <title>Rakete</title>
    </head>

    <body>
        <nav>
            <div id="navigation">
                <div class="wrapper">
                    <div id="logo"></div>
                    <label for="toggle">&#9776;</label>
                    <input type="checkbox" id="toggle"/>
                    <div id="menu">
                        <a href="#">Home</a>
                        <a href="#">About Us</a>
                        <a href="#">Contact</a>
                        <a href="#">Imprint</a>
                    </div>            
                </div>
            </div>
        </nav>

        <div id="main">
            <div class="wrapper">
               <div id="top-boxes">
                   <div class="box"></div>
                   <div class="box"></div>
                   <div class="box"></div>
                   <div class="box"></div>
                   <div class="box"></div>
               </div>

            <p>

Thanks in advance!

Solution

  • Use min-height instead of height for your #navigation styling.

    Old

    #navigation {
    ...
    height: 5em;
    ...
}

    New

    #navigation {
    ...
    min-height: 5em;
    ...
}

    Note: This solution is specific to your case. Different markup might needs different solution.
