我正在尝试用以下方法创建柔和的波浪CSS我遇到了一些麻烦。我现在正在使用边界半径来创建波浪，但它看起来更像云。我尝试使用transform: translateZ(180deg);但是div然后颜色是颠倒的。

</div>我建议使用内联手工编码SVG。你的形状非常简单掀起波澜SVG <path>元素很容易。
您需要了解的所有信息SVGMDN 上的路径 https://developer.mozilla.org/en-US/docs/Web/SVG/Tutorial/Paths。在下面的示例中，我使用了两个路径元素二次贝塞尔曲线 https://developer.mozilla.org/en-US/docs/Web/SVG/Tutorial/Paths#Bezier_Curves掀起波澜：
svg {
background: url('https://farm9.staticflickr.com/8461/8048823381_0fbc2d8efb.jpg') no-repeat center center;
background-size: cover;
width: 100%;
display: block;
}<svg viewbox="0 0 100 25">
<path fill="#9EAFFD" opacity="0.5" d="M0 30 V15 Q30 3 60 15 V30z" />
<path fill="#9EAFFD" d="M0 30 V12 Q30 17 55 12 T100 11 V30z" />
