最简单的方法是使用bootstrap和badge类

 <span class="badge">1</span>

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>

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。

.numberCircle { 这个特性:50%; 宽度:40像素; 高度:40像素; 显示:块; 浮:左; 边框:2px实体#000000; 颜色:# 000000; text-align:中心; margin-right: 5 px; ｝ <h3><span class="numberCircle">1</span> Regiones del Interior</h3>

不需要额外的工作。 谢谢约翰·诺埃尔·布鲁诺

.btn-circle.btn-xl { width: 70px; height: 70px; padding: 10px 16px; border-radius: 35px; font-size: 24px; line-height: 1.33; } .btn-circle { width: 30px; height: 30px; padding: 6px 0px; border-radius: 15px; text-align: center; font-size: 12px; line-height: 1.42857; } <div class="panel-body"> <h4>Normal Circle Buttons</h4> <button type="button" class="btn btn-default btn-circle"> <i class="fa fa-check"></i> </button> <button type="button" class="btn btn-primary btn-circle"> <i class="fa fa-list"></i> </button> </div>

如果是20或更低，你可以直接使用unicode字符①②…⑳
