<head>
<style>
#demo1 {
height: 100px;
background: linear-gradient(0deg, orange, blue);
}
#demo2 {
height: 100px;
background: linear-gradient(90deg, orange, blue);
}
#demo3 {
height: 100px;
background: linear-gradient(-90deg, orange, blue);
}
</style>
</head>
<body>
<h2>Linear Gradients</h2>
<div id = "demo1">0 degree</div><br>
<div id = "demo2">90 degrees</div><br>
