heart, heartrate and animated gear with css - css

Question

This is our logo:
We would like to create it with css and animate the gear, but as you can see if you run my code, I am struggling with following:
heart is not within the gear
if I put div of heart in the gear its animating to, but only the gear should animate
currently the heart-rate (blue line) isnt done with css, cause I dont know how to solve this
Do you know how to solve this?

Answer 1

Use position:absolute on the heart and position it in the center of the parent using top,left and transform
body {
background: #fff;
}
.parent {
display: flex;
height: 500px;
position:relative;
}
.gear {
position: relative;
width: 200px;
height: 200px;
margin: auto;
background: black;
border-radius: 50%;
animation-name: spin;
animation-duration: 4s;
animation-iteration-count: infinite;
animation-timing-function: linear;
}
.gear .center {
position: absolute;
top: 25px;
left: 25px;
z-index: 10;
width: 150px;
height: 150px;
background: #fff;
border-radius: 50%;
}
.tooth {
position: absolute;
top: -25px;
left: 75px;
z-index: 1;
width: 45px;
height: 250px;
background: black;
}
.tooth:nth-child(2) {
transform: rotate(45deg);
}
.tooth:nth-child(3) {
transform: rotate(90deg);
}
.tooth:nth-child(4) {
transform: rotate(135deg);
}
#keyframes spin {
