HTML
<!DOCTYPE html> <html>
<head>
<meta name="viewport" content="width=device-width,
initial-scale=1.0">
<link rel="stylesheet" href="./style.css">
</head>
<body>
<div>
<h2>GeekForGeeks</h2>
<img src=
</div>
</body>
</html>

CSS
/* style.css*/body { background-color: wheat;
} h2 {
font-size: 60px;
} @media only screen and (max-width: 1000px) {
body {
background-color: rgb(61, 239, 224);
}
h2 {
font-size: 45px;
}
img {
width: 350px;
height: 350px;
}
} @media only screen and (max-width: 600px) {
body {
background-color: green;
}
h2 {
font-size: 35px;

img {
width: 250px;
height: 250px;
