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;
}

The problem with most of the other answers here is you need to tweak the size of the outer container so that it is the perfect size based on the font size and number of characters to be displayed. If you are mixing 1 digit numbers and 4 digit numbers, it won't work. If the ratio between the font size and the circle size isn't perfect, you'll either end up with an oval or a small number vertically aligned at the top of a large circle. This should work fine for any amount of text and any size circle. Just set the width and line-height to the same value:

.numberCircle { 宽度:120 px; 行高:120 px; 这个特性:50%; text-align:中心; 字体大小:32像素; 边框:2px实体#666; ｝ < div class = " numberCircle " > < / div > 1 < div class = " numberCircle”> 100 < / div > < div class = " numberCircle”> 10000 < / div > < div class = " numberCircle”> 1000000 < / div >

如果您需要使内容更长或更短，您所需要做的就是调整容器的宽度以更好地适应。

在JSFiddle上可以看到。

.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>

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> .

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>
