SVG Wave animation at the bottom of a video background hero-CodePudding

I have a hero section on my webpage that I would like to create an animated wave animation at the bottom. The hero section displays a video background.

I have the video background working, and the animated waves, however, I am stuck with having a straight blue border between the two, as shown in the picture.

I can use a negative margin to bring the waves up on top of the video background but you end up with a hard border still.

It may be the way I have implemented the SVG but I'm a little lost now.

For sake of brevity, I have removed some elements (buttons, as this makes no difference) This is the HTML.

Can anyone give me some pointers on how to make the wave animation without a hard border?

CodePudding user response：

The class .waves has a background-color you need to remove. Then you can use a negative margin in order to pull the waves up. I also added position:relative to .waves so it applies the z-index.
