How to create a lollipop shape by stacking divs in a circular manner?

Question

How to stack divs in a circular manner in which last div should come beneath the first div but above the second last div. Is it possible with the css? any helps would be app

Answer 1

I would create this considering two elements (pseudo elements) and multiple radial gradient. You only need to create half the shape twice and rotate one of them.

.box {
  width:150px;
  height:150px;
  border-radius:100%;
  border:1px solid;
  position:relative;
  overflow:hidden;
}
.box::before,
.box::after{
  content:"";
  position:absolute;
  top:0;
  bottom:0;
  left:0;
  right:50%;
  background:
    /*we rotate by 30deg so will use :
       sin(30deg)*R = 0.5x75px   = 37.5px 
       cos(30deg)*R = 0.866x75px = 64.95px       
       10.05px = 75px - 64.95px;
       112.5px = 75px + 37.5px
       139.95px = 75px + 64.95px
       37.5px = 75px - 37.5px
       */
    radial-gradient(circle 75px at 139.95px 37.5px,red   98%,transparent 100%),
    radial-gradient(circle 75px at 112.5px 10.05px,white 98%,transparent 100%),
    radial-gradient(circle 75px at 75px    0,      red   98%,transparent 100%),
    radial-gradient(circle 75px at 37.5px  10.05px,white 98%,transparent 100%),
    radial-gradient(circle 75px at 10.05px 37.5px ,red   98%,transparent 100%),
    radial-gradient(circle 75px at 0       75px,   white 98%,transparent 100%),
    radial-gradient(circle 75px at 10.05px 112.5px,red   98%,transparent 100%);
}

.box::after {
 transform:rotate(180deg);
 transform-origin:right;
}

To make things more funny we can add CSS variables to easily control the shape:

.box {
  --R:50px; /*Radius*/
  --c1:red; /*first color*/
  --c2:#fff; /*second color*/
  
  --g1:var(--c1) 98%, transparent 100%;
  --g2:var(--c2) 98%, transparent 100%;
  width:calc(2*var(--R));
  height:calc(2*var(--R));
  border-radius:100%;
  border:1px solid;
  position:relative;
  overflow:hidden;
  display:inline-block;
  vertical-align:middle;
}
.box::before,
.box::after{
  content:"";
  position:absolute;
  top:0;
  bottom:0;
  left:0;
  right:50%;
  background:
     /*we rotate by 30deg so will use :
       sin(30deg)*R = 0.5xR   
       cos(30deg)*R = 0.866xR 
     */
    radial-gradient(circle var(--R) at calc(var(--R) + 0.866*var(--R)) calc(var(--R) - 0.5*var(--R))  ,var(--g1)),
    radial-gradient(circle var(--R) at calc(var(--R) + 0.5*var(--R))   calc(var(--R) - 0.866*var(--R)),var(--g2)),
    radial-gradient(circle var(--R) at var(--R)                        0                              ,var(--g1)),
    radial-gradient(circle var(--R) at calc(var(--R) - 0.5*var(--R))   calc(var(--R) - 0.866*var(--R)),var(--g2)),
    radial-gradient(circle var(--R) at calc(var(--R) - 0.866*var(--R)) calc(var(--R) - 0.5*var(--R))  ,var(--g1)),
    radial-gradient(circle var(--R) at 0                               var(--R)                        ,var(--g2)),
    radial-gradient(circle var(--R) at calc(var(--R) - 0.866*var(--R)) calc(var(--R) + 0.5*var(--R))  ,var(--g1));
}

/*the same shape rotated*/
.box::after {
 transform:rotate(180deg);
 transform-origin:right;
}

Note that Safari doesn't support the syntax with at (explained here How to make radial gradients work in Safari?) so here is anothe syntax:

.box {
  --R:50px; /*Radius*/
  --c1:red; /*first color*/
  --c2:#fff; /*second color*/
  
  --g1:var(--c1) 98%, transparent 100%;
  --g2:var(--c2) 98%, transparent 100%;
  width:calc(2*var(--R));
  height:calc(2*var(--R));
  border-radius:100%;
  border:1px solid;
  position:relative;
  overflow:hidden;
  display:inline-block;
  vertical-align:middle;
}
.box::before,
.box::after{
  content:"";
  position:absolute;
  top:0;
  bottom:0;
  left:0;
  right:50%;
  background:
     /*we rotate by 30deg so will use :
       sin(30deg)*R = 0.5xR   
       cos(30deg)*R = 0.866xR 
     */
    radial-gradient(farthest-side,var(--g1)) calc(var(--R) + 0.866*var(--R) - var(--R)) calc(var(--R) - 0.5*var(--R) - var(--R)),
     
    radial-gradient(farthest-side,var(--g1)) calc(var(--R) + 0.866*var(--R) - var(--R)) calc(var(--R) - 0.5*var(--R) - var(--R)),
    radial-gradient(farthest-side,var(--g2)) calc(var(--R) + 0.5*var(--R) - var(--R))   calc(var(--R) - 0.866*var(--R) - var(--R)),
    radial-gradient(farthest-side,var(--g1)) 0 calc(-1*var(--R)),
    radial-gradient(farthest-side,var(--g2)) calc(var(--R) - 0.5*var(--R) - var(--R))   calc(var(--R) - 0.866*var(--R) - var(--R)),
    radial-gradient(farthest-side,var(--g1)) calc(var(--R) - 0.866*var(--R) - var(--R)) calc(var(--R) - 0.5*var(--R) - var(--R)),
    radial-gradient(farthest-side,var(--g2)) calc(-1*var(--R))  0,
    radial-gradient(farthest-side,var(--g1)) calc(var(--R) - 0.866*var(--R) - var(--R)) calc(var(--R) + 0.5*var(--R) - var(--R));

/*the same shape rotated*/
.box::after {

 transform-origin:right center;
