我有一个背景图像，我想在它上面添加两个渐变滤镜...第一个滤镜是从右到左的蓝色滤镜，这是好的，但第二个滤镜是从上到下的黑色滤镜，它根本不光滑。我希望我的代码生成这个：https://dribbble.com/shots/2595241-VOID-Conference/attachments/516900但我的黑色过滤器毁了它。

您可以使用多个背景简化代码：
* {
box-sizing: border-box;
padding: 0;
margin: 0;
}
html,
body {
height: 100%;
}
.landing {
height: 100vh;
background:
linear-gradient(to bottom, transparent 40%, rgba(20, 20, 20,0.8) 80%),
linear-gradient(to right, rgba(0, 50, 150, 0.2) 0%, rgba(0, 25, 50, 0.2) 100%),
