Hide elements with jquery

I would like to hide individual element blocks that are identified by id`s.

I have used a jquery function to do this.


<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <meta name=”apple-mobile-web-app-capable” content=”yes “>
    <script type="text/javascript" src="http://code.jquery.com/jquery-3.7.1.min.js"></script>
    
    <script>

    function changeMenu(menu){
        $('#Slide_home').css({'display':'none'});
        $('#Slide_sub01').css({'display':'none'});
        $('#Slide_sub02').css({'display':'none'});  
        $('#Slide_'+menu).css({'display':'block'});
        }

    </script>

    <style>
    body { 
        margin: 0px; 
        padding: 0px; 
        background-color: rgb(53, 61, 64);  
        color: rgb(255, 255, 255); 
        height: 100%; 
        overflow-x: hidden; 
    } 

    #Menu {
        position: fixed;
        bottom: 0px;
        width: 100%;
        height: 100px;
        background-color: rgb(0, 0, 0);
        
        }
        
    .ButtonWrapper {
    display: flex;
    flex-direction: row;
    justify-content: center;
    text-align: center;
    }      
        
    .ButtonWrapper > div {
    margin-left: 50px;
    margin-top: 10px;  
    }
    </style>
      

</head>


<body>

<div id="Slide_home"> 

home
            
</div>

<div id="Slide_sub01">

01

</div>

<div id="Slide_sub02"> 

02

</div>

<div id="Menu">          
    <div class="ButtonWrapper">
        <div>
            <img class="" style="cursor:pointer" onClick="changeMenu('home');" src="01.png" alt="home"/>
        </div>

        <div>
            <img class="" style="cursor:pointer" onClick="changeMenu('sub01');" src="02.png" alt="sub_01"/>
        </div>

        <div>
            <img class="" style="cursor:pointer" onClick="changeMenu('sub02');" src="03.png" alt="sub_02"/>
        </div>
    </div>
</div>
                         
</body>
</html>

In principle the function works, when I press a button the corresponding other elements are hidden. But at the beginning all elements are visible. How can I display only the elements for home at the beginning?

Best regards
