我制作了一个色轮,除了最后一个元素占用更多空间且它的width
较大之外,它看起来不错。我怎样才能使我所有的span's
都具有相等的宽度
@for $i from 1 through 25 {
span:nth-child(#{$i}) {
border-top-color: hsl($i * 15, 50%, 50%);
border-left-color: transparent;
border-right-color: transparent;
border-bottom-color: transparent;
}
}
@for $i from 1 through 25 {
span:nth-child(#{$i}) {
transform: rotate($i * 14.4deg);
}
}
#colorWheel {
-webkit-animation: intro 3s ease;
width: 100px;
height: 100px;
margin: 0 auto;
position: relative;
transform-origin: 50px 150px;
transition: all 0.5s linear;
}
#colorWheel::before {
content: "";
width: 300px;
height: 300px;
overflow: hidden;
position: absolute;
top: -30px;
left: -130px;
border-radius: 100%;
border: 30px solid #ffffff;
z-index: 100;
}
#colorWheel span {
position: absolute;
-webkit-transform-origin: 50% 50%;
border-style: solid;
border-width: 150px 50px;
box-sizing: border-box;
}
<div id="colorWheel">
<span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span> <!-- 25 span's -->
</div>
这里是基于this previous answer的代码的优化:
@for $i from 1 through 25 {
span:nth-child(#{$i}) {
background-color: hsl($i * 15, 50%, 50%);
}
}
@for $i from 1 through 25 {
span:nth-child(#{$i}) {
transform: rotate($i * 14.4deg);
}
}
#colorWheel {
height: 300px;
width: 300px;
position:relative;
display:block;
margin:auto;
}
#colorWheel > * {
position:absolute;
top:0;
left:0;
right:0;
bottom:0;
border-radius:50%;
clip-path:polygon(
50% 50%,
50% 0%,
63% 0%);
}
