        </clipPath>
    </defs>
</svg>

Step 2 – Add CSS

We use some external CSS link to this code. No need to worry about this, copy and paste below code between <style></style> tag.

<head>
<link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Ubuntu:400,500&display=swap">
</head>

Copy and paste below code in your HTML editor between <style></style> tag.

<style>
* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

body {
  background-color: #2F3B45;
}

svg {
  width: 100vw;
}

footer {
  width: 100vw;
  bottom: 0;
  position: absolute;
  left: 0;
  display: flex;
  align-items: flex-end;
  padding-bottom: 3rem;
  justify-content: center;
  overflow: hidden;
  position: absolute;
  width: 100vw;
  height: 400px;
  bottom: 0;
  filter: url("#goo");
}
footer h1 {
  z-index: 2;
  color: white;
  font-family: "Ubuntu", sans-serif;
  font-weight: lighter;
  font-size: calc(2vmin + 8px);
}
footer h1 span {
  font-weight: bold;
  color: #FFA036;
  text-shadow: 0 0 15px rgba(255, 160, 54, 0.4);
}
footer::after {
  content: "";
  position: absolute;
  bottom: 0;
  left: 0;
  width: 100%;
  height: 225px;
  clip-path: url("#wave");
  background-color: #28323B;
}
@media only screen and (max-width: 700px) {
  footer::after {
    clip-path: none;
    height: 150px;
  }
}
footer .ball {
  width: 100px;
  height: 100px;
  border-radius: 50%;
  background-color: #28323B;
  position: absolute;
  animation: up 5s cubic-bezier(0.18, 0.89, 0.32, 1.28) infinite;
}
@media only screen and (max-width: 700px) {
  footer .ball {
    animation: up-small 5s cubic-bezier(0.18, 0.89, 0.32, 1.28) infinite;
  }
}

@keyframes up {
  0% {
    bottom: 0px;
    width: 100px;
    height: 100px;
  }
  50% {
    bottom: 200px;
  }
  100% {
    bottom: 0px;
    width: 0px;
    height: 0px;
  }
}
@keyframes up-small {
  0% {
    bottom: 0px;
    width: 100px;
    height: 100px;
  }
  50% {
    bottom: 150px;
  }
  100% {
    bottom: 0px;
    width: 0px;
    height: 0px;
  }
}

</style>

Step 3 – Add JavaScript

We use some external JavaScript link to this code. No need to worry about this, copy and paste below code between <head></head> tag.

<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
</head>

And also copy and paste below JavaScript code between <script></script> tag.

<script>
function generateBalls() {
  for (var i = 0; i < Math.floor(window.innerWidth / 20); i++) {
    $(".gooey-animations").append(`
    <div class="ball"></div>
  `);
    var colors = ["#28323B", "#FFA036"];
    $(".ball")
      .eq(i)
      .css({
        bottom: "0px",
        left: Math.random() * window.innerWidth - 100,
        "animation-delay": Math.random() * 5 + "s",
        transform: "translateY(" + Math.random() * 10 + "px)",
        "background-color": colors[i % 2]
      });
  }
}
generateBalls();

window.addEventListener("resize", function (e) {
  $(".gooey-animations .ball").remove();
  generateBalls();
});

</script>

At the end we will have something like this. You can change fonts, colors, backgrounds and all things that you want. Enjoy it.
