I'd like to animate the top of a div which is filled with a blue sea like color.
And I'd like the animation to feint little sea waves. Knowing that my displaying is for a very little resolution (120px width).
I tried with particles-js, and it was cool to learn how to add a motion effect, but it doesn't make my top section looking like sea waves.
And then I tried with CSS, trying to understand some existing code and the best I've done for the moment is that:
:root {
--bg-color: #dfffa9;
--wave-color: #0048ff;
--animation-time: 4s;
--max-height: 15px;
--circle-offset: -1.5%;
--wave-width: 55%;
--height-wave-up: 109%;
--height-wave-down: 100%;
--top-wave-up: 60%;
--top-wave-down: 40%;
--border-radius-right-up: 100% 50%;
--border-radius-left-up: 50% 100%;
}
body {
margin: 0;
overflow: hidden;
background: var(--wave-color);
}
.container {
position: relative;
height: 10vh;
background: var(--bg-color);
}
.wave {
position: absolute;
bottom: 0;
width: 100%;
height: var(--max-height);
background: var(--bg-color);
animation: beWavy var(--animation-time) infinite linear;
}
.wave::before,
.wave::after {
content: "";
display: block;
position: absolute;
border-radius: var(--border-radius-right-up);
width: var(--wave-width);
}
.wave::before {
height: var(--height-wave-up);
background-color: var(--wave-color);
right: var(--circle-offset);
top: var(--top-wave-up);
animation: beWavyBefore var(--animation-time) infinite step-end;
}
.wave::after {
height: var(--height-wave-down);
background-color: var(--bg-color);
left: var(--circle-offset);
top: var(--top-wave-down);
animation: beWavyAfter var(--animation-time) infinite step-end;
}
@keyframes beWavy {
0% {
animation-timing-function: ease-in;
height: var(--max-height);
}
25% {
animation-timing-function: ease-out;
height: 0;
}
50% {
animation-timing-function: ease-in;
height: var(--max-height);
}
75% {
animation-timing-function: ease-out;
height: 0;
}
100% {
animation-timing-function: ease-in;
height: var(--max-height);
}
}
@keyframes beWavyBefore {
25% {
background-color: var(--bg-color);
height: var(--height-wave-down);
top: var(--top-wave-down);
border-radius: var(--border-radius-left-up);
}
75% {
background-color: var(--wave-color);
height: var(--height-wave-up);
top: var(--top-wave-up);
border-radius: var(--border-radius-right-up);
}
}
@keyframes beWavyAfter {
25% {
background-color: var(--wave-color);
height: var(--height-wave-up);
top: var(--top-wave-up);
border-radius: var(--border-radius-left-up);
}
75% {
background-color: var(--bg-color);
height: var(--height-wave-down);
top: var(--top-wave-down);
border-radius: var(--border-radius-right-up);
}
}

But 2 waves only seems really repetitve and low cost haha. I want random waves with random starting points. So if someone could help me understand how it works exactly, thanks.
