创建CSS半圆 [英] Create CSS Semi-Circles

问题描述

我有一个实心圆圈，其中包含这样的数字：

如何将其分成两个半圆，这样我可以在其中存储两个不同的数字，就像这样：

我的CSS如下：

  .oval {
 display：inline-block; 
宽度：75像素； 
高度：75像素； 
边界半径：50％； 
背景：＃000000； 
颜色：白色； 
行高：75px； 
 font-size：中; 
} 
  

解决方案

您可以使用边界半径

  .left-half，.right-half {float：left;宽度：40px；高度：80px；行高：80px；白颜色;文本对齐：居中；边距：0 1px;背景：黑色；}。left-half：nth-​​child（1）{border-radius：80px 0 0 80px;}。right-half：nth-​​child（2）{border-radius：0 80px 80px 0;}  

 < div class = circle> < div class = left-half> 21< / div> < div class = right-half> 12< / div>< / div>  

或者您可以使用 SVG

  .text { font-size：16px;填充：白色；}  

 < svg width = 105.5 px height = 97.874px viewBox = 0 0 105.5 97.874> < path d = M50.423,0.609v96.76c-26.72,0-48.38-21.66-48.38-48.38C2.043,22.269,23.703,0.609,50.423,0.609z /> < path d = M103.526,49.494c0,26.72-21.66,48.38-48.38,48.38V1.114C81.866,1.114,103.526,22.774,103.526,49.494z /> < text transform = matrix（1 0 0 1 20.0771 52.5107） class = text> 21< / text> < text transform = matrix（1 0 0 1 73.1807 53.0166） class = text> 12< / text>< / svg>

更新：您也可以只创建两个跨度的圆并在中间加上 pseudo-class

  .circle {width：70px;高度：70px；背景：黑色；边界半径：50％；显示：flex; align-items：居中;白颜色;位置：相对；}跨度{flex：1; text-align：center;}。circle：before {content：;宽度：2px；位置：绝对；高度：100％;背景：白色；最高：0;左：50％；转换：translateX（-50％）;}  

 < div class = circle> < span> 12< span> span> 24< / span>< / div>  

I have a filled circle that contains a number like so:

How would I go about splitting this into two semi-circles, so that I can store two different numbers within it, like so:

My CSS is as follows:

.oval {
    display: inline-block;
    width: 75px;
    height: 75px;
    border-radius: 50%;
    background: #000000;
    color: white;
    line-height: 75px;
    font-size: medium;
}

解决方案

You can use border-radius

.left-half,
.right-half {
  float: left;
  width: 40px;
  height: 80px;
  line-height: 80px;
  color: white;
  text-align: center;
  margin: 0 1px;
  background: black;
}
.left-half:nth-child(1) {
  border-radius: 80px 0 0 80px;
}
.right-half:nth-child(2) {
  border-radius: 0 80px 80px 0;
}

<div class="circle">
  <div class="left-half">21</div>
  <div class="right-half">12</div>
</div>

Or you can use SVG

.text {
  font-size: 16px;
  fill: white;
}

<svg width="105.5px" height="97.874px" viewBox="0 0 105.5 97.874">
  <path d="M50.423,0.609v96.76c-26.72,0-48.38-21.66-48.38-48.38C2.043,22.269,23.703,0.609,50.423,0.609z" />
  <path d="M103.526,49.494c0,26.72-21.66,48.38-48.38,48.38V1.114C81.866,1.114,103.526,22.774,103.526,49.494z" />
  <text transform="matrix(1 0 0 1 20.0771 52.5107)" class="text">21</text>
  <text transform="matrix(1 0 0 1 73.1807 53.0166)" class="text">12</text>
</svg>

Update: You could also just create circle with two spans inside and add one line in middle with pseudo-class

.circle {
  width: 70px;
  height: 70px;
  background: black;
  border-radius: 50%;
  display: flex;
  align-items: center;
  color: white;
  position: relative;
}
span {
  flex: 1;
  text-align: center;
}
.circle:before {
  content: "";
  width: 2px;
  position: absolute;
  height: 100%;
  background: white;
  top: 0;
  left: 50%;
  transform: translateX(-50%);
}

<div class="circle">
  <span>12</span><span>24</span>
</div>
