Media queries for the header background image display

I am currently working on a small web project and I want to change the background image in the header section while also making it responsive. I attempted to use a class called "header_accueil" in my header to distinguish different sections of the site, but unfortunately, it did not work as expected. Despite searching through various forums, I have been unable to find a solution to my issue.

Below are snippets of my CSS and HTML code:

@media only screen and (min-device-width : 320px) and (max-device-width : 480px) {
    .header_accueil { 
        background: url('images/4585760.jpg') no-repeat center center fixed; 
        -webkit-background-size: cover;
        -moz-background-size: cover;
        -o-background-size: cover;
        background-size: cover;
        display:block;
        }
    }
<!doctype html>
<html lang="fr">
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Site</title>
  <link rel="stylesheet" href="style.css">
  <script src="script.js"></script>
</head>
<body>
    <header class="header_accueil">

    </header>

</body>
</html>

Additionally, here is the directory where all my files are stored:

Any assistance you can provide would be greatly appreciated. Thank you.

Answer №1

I made updates to both my HTML and CSS code :

@media only screen and (min-width : 320px) and (max-width : 480px) {

    .header_accueil {
    
    background: url('images/4585760.jpg') no-repeat center center fixed;
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
    display:block;
    height: 1000px;
    
    }
}

@media only screen and (min-width : 1224px){
    body{
        display: none;
    }
}
<!doctype html>
<html lang="fr">
<head>
<meta charset="utf-8>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Website Title</title>
<link rel="stylesheet" href="style.css">
<script src="script.js"></script>
</head>
<body>
    <header class="header_accueil">
        <p>test</p>
        <p>test</p>
        <p>test</p>
        <p>test</p>
        <p>test</p>
        <p>test</p>
        <p>test</p>
    </header>

</body>
</html>

Despite these changes, there is no visible difference in the output.
