Elementor includes some great shape dividers, which allows you to create separator effects between two sections. They are extremely flexible, with options to change the size of the shapes, invert them, or flip them over. The shapes are also very lightweight SVG files, that only load when you need them to, and only after the page has finished loading, so page speed isn't affected.
It's difficult to imagine how flexible these shapes are, so take a look at the video from Elementor.
The process couldn't be simpler. You just go to the section's Style tab, and choose the type of shape divider you'd like, from the dropdown list provided. Then spend some time playing with the various options for height, color, etc., until it looks exactly the way you want. It's so easy, there's really no point in trying to create a list of steps. Go try it. It's fun!
