我想把一个数字围成一个圆，就像下图所示:
这可能吗?它是如何实现的?

下面是JSFiddle的演示和代码片段:
/* Creating a number within a circle using CSS */ .numberCircle { font-family: "OpenSans-Semibold", Arial, "Helvetica Neue", Helvetica, sans-serif; display: inline-block; color: #fff; text-align: center; line-height: 0px; border-radius: 50%; font-size: 12px; min-width: 38px; min-height: 38px; } .numberCircle span { display: inline-block; padding-top: 50%; padding-bottom: 50%; margin-left: 1px; margin-right: 1px; } /* Some Back Ground Colors */ .clrGreen { background: #51a529; } .clrRose { background: #e6568b; } .clrOrange { background: #ec8234; } .clrBlueciel { background: #21adfc; } .clrMauve { background: #7b5d99; } <span class="numberCircle clrGreen"><span>8</span></span> <span class="numberCircle clrRose"><span>80</span></span> <span class="numberCircle clrOrange"><span>800</span></span> <span class="numberCircle clrMauve"><span>8000</span></span>

如果是20或更低，你可以直接使用unicode字符①②…⑳

最简单的方法是使用bootstrap和badge类
<span class="badge">1</span>
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;
}
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。
