Wave Height Animation in CSS

If you have worked with waves in CSS animations, you might have encountered options to configure wave height without creating rigid lines and artificiality. For this task, you should use specific techniques and methods that can help create realistic and fluent animations.

The first step to create a good wave animation is to use CSS properties like keyframes and transform. You should move the wave using these capabilities to make it look natural. For instance, you can use percentages to change wave height over a complete rotation. This process helps you achieve gradual and seamless transformations.

The second important point is working with cubic-bezier, which allows you to replace a straight line with a smooth and fluent motion. This issue would make wave movement appear more natural, instead of creating any rigid line during wave production.

Additionally, increasing duration of animation can help you achieve desired results. A shorter time may cause the animation to appear artificial and inconsistent, while a longer duration can make movements look smoother.

Finally, you can use the scale property in combination with rotate to create ripple effects as part of wave animation. This technique enables you to create subtle changes in size and angle of the wave, thus making it look more alive and dynamic without creating a rigid line.

<style>
  .wave {
    position: relative;
    width: 100%;
    height: 150px;
    background: lightblue;
    overflow: hidden;
  }
  .wave::before {
    content: '';
    position: absolute;
    top: 50%;
    left: 0;
    width: 200%;
    height: 200px;
    background: rgba(255, 255, 255, 0.5);
    border-radius: 50%;
    transform: translate(-50%, -50%) scale(1.3);
    animation: waveMove 3s infinite cubic-bezier(0.25, 0.1, 0.25, 1);
  }
  @keyframes waveMove {
    0% {transform: translate(-50%, -50%) scale(1.3);}
    50% {transform: translate(-45%, -55%) scale(1.35);}
    100% {transform: translate(-50%, -50%) scale(1.3);}
  }
</style>
<div class="wave"></div>
