Draw the head:

.head { position: absolute; width: 7em; height: 7em; background-color: currentColor; border-radius: 50%; right: 0; }

Draw the body:

.body { position: absolute; width: 6.2em; height: 14.4em; background-color: currentColor; top: 7em; border-radius: 100% 20% 0 0; }

Draw the feet, now only one can be seen Only one foot, because the two feet overlap each other, and you can see the two feet when you move:

.feet::before, .feet::after { content: ''; position: absolute; width: 4em; height: 1.4em; background-color: white; bottom: 0; left: -1.6em; border-radius: 1em 80% 0.4em 0.4em; }

Copy after login

Use pseudo elements to draw shadows:

.man::before { content: ''; position: absolute; width: 12em; height: 0.8em; background-color: rgba(0, 0, 0, 0.1); bottom: -0.2em; left: -3em; border-radius: 50%; }

Next, add animation Effect.

Add the animation effect of walking, and make the animation time of the two feet staggered:

.feet::before, .feet::after { animation: feet-animation 2s ease-in-out infinite; } .feet::after { animation-delay: 1s; } @keyframes feet-animation { 20% { transform: translateX(3.4em) translateY(-1.6em) rotate(4deg); } 30% { transform: translateX(4.6em) translateY(-1em) rotate(0deg); } 40% { transform: translateX(5.6em) translateY(-0.6em) rotate(4deg); } 44% { transform: translateX(5.6em) translateY(0) rotate(0deg); } }

Copy after login

Add the animation effect of the undulating head and body:

.head, .body { animation: body-animation 4s ease-in-out infinite; } @keyframes body-animation { 0%, 100% { transform: translateY(0) skewX(-2deg); } 25%, 75% { transform: translateY(0.5em) skewX(0deg); } 50% { transform: translateY(0) skewX(0deg); } }

Copy after login

Increase the shadow area with the body Animation effects that change due to movement:

.man::before { animation: shadow-animate 4s ease-in-out infinite; } @keyframes shadow-animate { 0%, 50%, 100% { transform: scale(1); } 25%, 75% { transform: scale(1.15); } }
