这是我的方法，用平方法。优点是它适用于不同的值，但你需要两个跨度。

.circle { display: inline-block; border: 1px solid black; border-radius: 50%; position: relative; padding: 5px; } .circle::after { content: ''; display: block; padding-bottom: 100%; height: 0; opacity: 0; } .num { position: absolute; top: 50%; transform: translateY(-50%); } .width_holder { display: block; height: 0; overflow: hidden; } <div class="circle"> <span class="width_holder">1</span> <span class="num">1</span> </div> <div class="circle"> <span class="width_holder">11</span> <span class="num">11</span> </div> <div class="circle"> <span class="width_holder">11111</span> <span class="num">11111</span> </div> <div class="circle"> <span class="width_holder">11111111</span> <span class="num">11111111</span> </div>

对于根据内容变化的圆圈大小，这应该是有效的:

.numberCircle { display: inline-block; line-height: 0px; border-radius: 50%; border: 2px solid; font-size: 32px; } .numberCircle span { display: inline-block; padding-top: 50%; padding-bottom: 50%; margin-left: 8px; margin-right: 8px; } <span class="numberCircle"><span>30</span></span> <span class="numberCircle"><span>1</span></span> <span class="numberCircle"><span>5435</span></span> <span class="numberCircle"><span>2</span></span> <span class="numberCircle"><span>100</span></span>

它依赖于内容的宽度加上margin- s来确定半径，然后使用padding- s扩展高度以匹配。margin-'s需要根据字体大小进行调整。

更新以删除内部元素:

.numberCircle { display: inline-block; border-radius: 50%; border: 2px solid; font-size: 32px; } .numberCircle:before, .numberCircle:after { content: '\200B'; display: inline-block; line-height: 0px; padding-top: 50%; padding-bottom: 50%; } .numberCircle:before { padding-left: 8px; } .numberCircle:after { padding-right: 8px; } <span class="numberCircle">30</span> <span class="numberCircle">1</span> <span class="numberCircle">5435</span> <span class="numberCircle">2</span> <span class="numberCircle">100</span>

使用伪元素强制高度。垂直对齐需要零宽度空间。将line-height:0px从外层移到伪层，这样在IE8降级时至少是可见的。

改进第一个答案，只需去除填充，并添加line-height和vertical-align:

.numberCircle {
   border-radius: 50%;       

   width: 36px;
   height: 36px;
   line-height: 36px;
   vertical-align:middle;

   background: #fff;
   border: 2px solid #666;
   color: #666;

   text-align: center;
   font: 32px Arial, sans-serif;
}

这是我的方法，用平方法。优点是它适用于不同的值，但你需要两个跨度。

.circle { display: inline-block; border: 1px solid black; border-radius: 50%; position: relative; padding: 5px; } .circle::after { content: ''; display: block; padding-bottom: 100%; height: 0; opacity: 0; } .num { position: absolute; top: 50%; transform: translateY(-50%); } .width_holder { display: block; height: 0; overflow: hidden; } <div class="circle"> <span class="width_holder">1</span> <span class="num">1</span> </div> <div class="circle"> <span class="width_holder">11</span> <span class="num">11</span> </div> <div class="circle"> <span class="width_holder">11111</span> <span class="num">11111</span> </div> <div class="circle"> <span class="width_holder">11111111</span> <span class="num">11111111</span> </div>

我在这里的解决方案-这很容易允许不同的大小和颜色，并连接到CMS进行编辑控制。IE退化为平方。

HTML:

<div class="circular-label label-outer label-size-large label-color-pink">
    <div class="label-inner"> 
        <span>Fashion & Beauty</span>
    </div>
</div>

CSS:

.circular-label {
    overflow: hidden;
    z-index: 100;
    vertical-align: middle;
    font-size: 11px;
    -webkit-box-shadow:0 3px 3px rgba(0, 0, 0, 0.2);
    -moz-box-shadow:0 3px 3px rgba(0, 0, 0, 0.2);
    box-shadow: 3px 3px 3px rgba(0, 0, 0, 0.2);
}
.label-inner {
    width: 85%;
    height: 85%;
    -moz-border-radius: 50%;
    -webkit-border-radius: 50%;
    border-radius: 50%;
    border: 2px dotted white;
    vertical-align: middle;
    margin: auto;
    top: 5%;
    position: relative;
    overflow: hidden;
}
.label-inner > span {
    display: table;
    text-align: center;
    vertical-align: middle;
    font-weight: bold;
    text-transform: uppercase;
    width: 100%;
    position: absolute;
    margin: auto;
    margin-top: 38%;
    font-family:'ProximaNovaLtSemibold';
    font-size: 13px;
    line-height: 1.0em;
}
.circular-label.label-size-large {
    width: 110px;
    height: 110px;
    -moz-border-radius: 55px;
    -webkit-border-radius: 55px;
    border-radius: 55px;
    margin-top:-55px;
}
.circular-label.label-size-med {
    width: 76px;
    height: 76px;
    -moz-border-radius: 38px;
    -webkit-border-radius: 38px;
    border-radius: 38px;
    margin-top:-38px;
}
.circular-label.label-size-med .label-inner > span {
    margin-top: 33%;
}
.circular-label.label-size-small {
    width: 66px;
    height: 66px;
    -moz-border-radius: 33px;
    -webkit-border-radius: 33px;
    border-radius: 33px;
    margin-top:-33px;
}

要知道怎么做并不难。更大的问题是，是否有可能使圆圈的尺寸与内容相匹配。

目前我认为这是不可能的。有人知道吗?

在css中做这样的事情吗

 div {
    width: 10em; height: 10em; 
    -webkit-border-radius: 5em; -moz-border-radius: 5em;
  }
  p {
    text-align: center; margin-top: 4.5em;
  }

使用段落标签来书写文本。希望这能有所帮助
