您可以尝试运行以下代码以在CSS3中实现多色渐变-
<html>
<head>
<style>
#grad2 {
height: 100px;
background: -webkit-linear-gradient(red, orange, yellow, red, blue, green,pink);
background: -o-linear-gradient(red, orange, yellow, red, blue, green,pink);
background: -moz-linear-gradient(red, orange, yellow, red, blue, green,pink);
background: linear-gradient(red, orange, yellow, red, blue, green,pink);
}
</style>
</head>
<body>
<div id = "grad2"></div>
</body>
</html>
