<p>我正在制作一个锥形渐变的动画，但颜色变化不够平滑
我看过各种文章，但无法正确复制它们
你可以在这里找到我的代码：</p>
<pre class="brush:php;toolbar:false;"><style>
body{
min-height: 100vh;
display: flex;
align-items: center;
justify-content: center;
}
.pyramid {
width: 500px;
height: 500px;
background-image: conic-gradient(red 135deg, green 135deg,yellow 165deg, yellow 165deg);
clip-path: polygon(50% 50%, 0% 100%, 100% 100%);
animation: change 1s ease infinite;
}
.pyramid:hover{
background-image: conic-gradient(red 135deg, #cadfca 135deg,#dddd3f 165deg, #aeae30 165deg);
}
@keyframes change{
0%{
background-image: conic-gradient(red 135deg, yellow 135deg,yellow 165deg, lightpink 165deg);
/*background: red;*/
}
50%{
background-image: conic-gradient(red 135deg, #cadfca 135deg,#dddd3f 165deg, #aeae30 165deg);
}
100%{
background-image: conic-gradient(red 135deg, #565644 135deg,#838314 165deg, #a68f03 165deg)
}
}
</style>
</head>

<p>如何使其变化更加平滑</p>
背景图像在您想要的方式中无法平滑地进行动画处理。
然而，您可以平滑地动画化不透明度，因此一种获得效果的方法是将两个背景图像放在彼此上方，并改变它们的不透明度，使它们逐渐从一个变为另一个。
在您的情况下，您可以将背景图像放在伪元素的before和after上，而不是放在元素本身上。
它们具有相同的动画效果，但一个从中间开始（当不透明度为1时）。
当总持续时间只有1秒时，很难意识到这种混合效果，因此此代码片段增加了持续时间，以便您可以看到效果。
当然，您可以根据需要更改时序。
更改还是线性的，以便覆盖始终提供“整体”图像而不是半透明图像。
