Code interpretation

Define dom, the page contains 2 elements, representing rabbits and clouds respectively:

<div></div>
<div></div>

Centered display:

body {
    margin: 0;
    height: 100vh;
    display: flex;
    align-items: center;
    justify-content: center;
    background: linear-gradient(midnightblue, black);
    font-size: 30px;
}

Draw the rabbit’s body:

.rabbit {
    width: 5em;
    height: 3em;
    color: whitesmoke;
    background: currentColor;
    border-radius: 70% 90% 60% 50%;
}

Use radial gradient to draw the rabbit’s eyes:

.rabbit {
    background: 
        radial-gradient(
            circle at 4.2em 1.4em,
            #333 0.15em,
            transparent 0.15em
        ), /* eye */
        currentColor;
}

Use pseudo elements to draw the rabbit’s right ear:

.rabbit::before {
    content: '';
    position: absolute;
    width: 0.75em;
    height: 2em;
    background-color: currentColor;
    border-radius: 50% 100% 0 0;
    transform: rotate(-30deg);
    top: -1em;
    right: 1em;
}

Use shadow to draw the rabbit’s left ear:

.rabbit::before {
    border: 0.1em solid;
    border-color: gainsboro transparent transparent gainsboro;
    box-shadow: -0.5em 0 0 -0.1em;
}

Use pseudo elements to draw the rabbit’s tail:

.rabbit::after {
    content: '';
    position: absolute;
    width: 1em;
    height: 1em;
    background-color: currentColor;
    border-radius: 50%;
    left: -0.3em;
    top: 0.5em;
}

Draw the rabbit’s legs with shadow:

.rabbit::after {
    box-shadow: 
        0.5em 1em 0,
        4em 1em 0 -0.2em,
        4em 1em 0 -0.2em;
}

Draw the rabbit’s shadow:

.rabbit {
    box-shadow: -0.2em 1em 0 -0.75em #333;
}

Draw a cloud:

.clouds {
    width: 2em;
    height: 2em;
    color: whitesmoke;
    background: currentColor;
    border-radius: 100% 100% 0 0;
    transform: translate(0, -5em);
}

.clouds::before,
.clouds::after {
    content: '';
    position: absolute;
    background-color: currentColor;
    bottom: 0;
}

.clouds::before {
    width: 1.25em;
    height: 1.25em;
    border-radius: 100% 100% 0 100%;
    left: -30%;
}

.clouds::after {
    width: 1.5em;
    height: 1.5em;
    border-radius: 100% 100% 100% 0;
    right: -30%;
}

Use shadow to draw 2 A cloud:

.rabbit {
    z-index: 1;
}

.clouds,
.clouds::before,
.clouds::after {
    box-shadow: 
    5em 2em 0 -0.3em,
    -2em 2em 0 0;
}

Next, create the animation effect.
Add the rabbit jumping animation:

.rabbit {
    animation: hop 3s linear infinite;
}

@keyframes hop {
    20% {
        transform: rotate(-10deg) translate(1em, -2em);
        box-shadow: -0.2em 1em 0 -1em #333;
    }

    40% {
        transform: rotate(10deg) translate(3em, -4em);
        box-shadow: -0.2em 3.25em 0 -1.1em #333;
    }

    60%, 75% {
        transform: rotate(0deg) translate(4em, 0);
        box-shadow: -0.2em 1em 0 -0.75em #333;
    }
}

Add the rabbit’s leg stretching animation:

.rabbit::after {
    animation: kick 3s infinite linear;
}

@keyframes kick {
    40% {
        box-shadow: 
            0.5em 2em 0,
            4.2em 1.75em 0 -0.2em,
            4.4em 1.9em 0 -0.2em;
    }
}

Add the cloud fluttering animation:

.clouds {
    animation: cloudy 3s infinite linear forwards;
    filter: opacity(0);
}

@keyframes cloudy {
    40% {
        transform: translate(-3em, -5em);
        filter: opacity(0.75);
    }

    55% {
        transform: translate(-4em, -5em);
        filter: opacity(0);
    }
}

Done!
