CodePudding user response：

You could use a clip-path.

There are two ways to do it:

Create an SVG that has a path of the shape you want and use that as the clip-path: https://codesandbox.io/s/bezier-curve-clip-path-h8x8l?from-embed=&file=/index.html
Generate a polygon yourself with code which approximates the curve you want. Have a look at this question here: Create clip-path wave css edges
