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>

虽然迟到了，但下面是我用https://codepen.io/jnbruno/pen/vNpPpW给出的解决方案

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>

虽然迟到了，但这里有一个对我有效的自助解决方案。我使用Bootstrap 4:

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/> 身体< > <div class="行mt-4"> < div class = " col-md-12”> <span class="bg-dark text-white round -circle px-3 py-1 mx-2 h3">1</span> <span class="bg-dark text-white round -circle px-3 py-1 mx-2 h3">2</span> <span class="bg-dark text-white round -circle px-3 py-1 mx-2 h3">3</span> < / div > < / div > 身体< / >

基本上，您将bg-dark text-white圆圆px-3 py-1 mx-2 h3类添加到<span>(或其他)元素中，就完成了。

请注意，如果内容有多个数字，则可能需要调整边距和填充类。

三十点的答案是对的，但少了一点。你需要添加位置:相对，如果你想在圆中有居中值，还包括不同范围的数字。 例如123;

HTML:

< div级30 =“numberCircle > < / div >

CSS:

.numberCircle {    

border-radius: 50%;
behavior: url(PIE.htc); /* remove if you don't care about IE8 */
width: 36px;
height: 36px;
padding: 8px;
position: relative;
background: #fff;
border: 2px solid #666;
color: #666;
text-align: center;

font: 32px Arial, sans-serif;
}

但最简单的解决方案是使用Bootstrap

<span class="badge" style ="float:right">123</span> .

你可以使用

span.red { background: red; border-radius: 0.8em; -moz-border-radius: 0.8em; -webkit-border-radius: 0.8em; color: #ffffff; display: inline-block; font-weight: bold; line-height: 1.6em; margin-right: 15px; text-align: center; width: 1.6em; } span.grey { background: #cccccc; border-radius: 0.8em; -moz-border-radius: 0.8em; -webkit-border-radius: 0.8em; color: #fff; display: inline-block; font-weight: bold; line-height: 1.6em; margin-right: 15px; text-align: center; width: 1.6em; } span.green { background: #5EA226; border-radius: 0.8em; -moz-border-radius: 0.8em; -webkit-border-radius: 0.8em; color: #ffffff; display: inline-block; font-weight: bold; line-height: 1.6em; margin-right: 15px; text-align: center; width: 1.6em; } span.blue { background: #5178D0; border-radius: 0.8em; -moz-border-radius: 0.8em; -webkit-border-radius: 0.8em; color: #ffffff; display: inline-block; font-weight: bold; line-height: 1.6em; margin-right: 15px; text-align: center; width: 1.6em; } span.pink { background: #EF0BD8; border-radius: 0.8em; -moz-border-radius: 0.8em; -webkit-border-radius: 0.8em; color: #ffffff; display: inline-block; font-weight: bold; line-height: 1.6em; margin-right: 15px; text-align: center; width: 1.6em; } <h1><span class="grey">1</span>A grey circle with number inside</h1> <h1><span class="red">2</span>A red circle with number inside</h1> <h1><span class="blue">3</span>A blue circle with number inside</h1> <h1><span class="green">4</span>A green circle with number inside</h1> <h1><span class="pink">5</span>A pink circle with number inside</h1>
