如何以循环方式堆叠div,使得最后一个div应该位于第一个div之下但位于第二个div之上。 CSS可能吗?任何帮助将不胜感激。

我将考虑两个元素(伪元素)和多个径向渐变来创建此模型:
.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 center;
}
<div class="box">
</div>
为了使事情更有趣,我们可以添加CSS变量:
.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 center;
}
<div class="box"></div>
<div class="box" style="--R:80px;--c1:blue"></div>
<div class="box" style="--R:100px;--c1:green;--c2:yellow"></div>
<div class="box" style="--R:150px;--c1:white;--c2:pink"></div>
请注意,Safari不支持at
的语法(此处为How to make radial gradients work in Safari?的解释),因此这里是另一种语法:
.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));
background-size:calc(2*var(--R)) calc(2*var(--R));
background-repeat:no-repeat;
}
/*the same shape rotated*/
.box::after {
transform:rotate(180deg);
transform-origin:right center;
}
<div class="box"></div>
<div class="box" style="--R:80px;--c1:blue"></div>

<div class="box" style="--R:150px;--c1:white;--c2:pink"></div>
答案 1 :(得分:5)
我的方法是使用可重用的SVG <symbol>
,其路径由quadratic-bézier曲线形成:
#svg-lollipop path { transform-origin: 50% 50%; }
#svg-lollipop path:nth-child(2) { transform: rotateZ(60deg); }
#svg-lollipop path:nth-child(3) { transform: rotateZ(120deg); }
#svg-lollipop path:nth-child(4) { transform: rotateZ(180deg); }
#svg-lollipop path:nth-child(5) { transform: rotateZ(240deg); }
#svg-lollipop path:nth-child(6) { transform: rotateZ(300deg); }
.lollipop {
width: 50%;
overflow: hidden;
border-radius: 50%;
position: relative;
margin: 20px;
}
.lollipop::before {
content: "";
padding-bottom: 100%;
display: block;
}
.lollipop svg {
position: absolute;
left: 0;
top: 0;
right: 0;
bottom: 0;
fill: currentColor;
}
<svg style="display: none;">
<symbol id="svg-lollipop">
<path d="M150,150 Q75,185 0,150 H0 V63.6 Q75,150 150,150 z" />
<path d="M150,150 Q75,185 0,150 H0 V63.6 Q75,150 150,150 z" />
<path d="M150,150 Q75,185 0,150 H0 V63.6 Q75,150 150,150 z" />
<path d="M150,150 Q75,185 0,150 H0 V63.6 Q75,150 150,150 z" />
<path d="M150,150 Q75,185 0,150 H0 V63.6 Q75,150 150,150 z" />
<path d="M150,150 Q75,185 0,150 H0 V63.6 Q75,150 150,150 z" />
</symbol>
</svg>
<div class="lollipop" style="background-color: #FFF; color:#E92120;">
<svg viewBox="0 0 300 300"><use xlink:href="#svg-lollipop"></use></svg>
</div>
<div class="lollipop" style="background-color: #004991; color:#007BC1;">
<svg viewBox="0 0 300 300"><use xlink:href="#svg-lollipop"></use></svg>
</div>
工作方式
将相同形状克隆6次并旋转以填充整个svg。在此示例中,每个彩色形状都有一个角度α = 30deg
。
然后从三角学中我们可以找到曲线的原点的坐标:在路径中, y坐标 63.6
的取值为150 - (150 * tan(α))
,因此如果需要更改形状和角度的数量,您可以轻松找到自己的原点(quadratic curves确实很容易绘制)。
最后,外包装具有一个border-radius
和一个隐藏的overflow
,以提供圆形形状。
最终结果也很敏感,因为外部包装器保持其1:1
的宽高比。
可以通过在容器上设置background-color
来更改白色区域,而可以使用color
属性({{1}的fill
属性}元素为方便起见设置为svg
。
我以后发现的东西
如果在包装纸上添加currentColor
,则看起来更像是充气的沙滩气球,而不是棒棒糖。
机缘巧合
