SVG Waves. You can customize the background on top, bottom or center of the waves. As background supported: one background color, linear and radial gradient, set pictures (support tiles and cover). You can also set the color of the waves, height and their speed. You can enable the parallax effect when a picture is used as the background (in cover mode). If you need to make height without content inside the stack, then you can specify padding at the top and bottom.
