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。

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>

最简单的方法是使用bootstrap和badge类

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

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> .

对于0到99的数字来说，这样做是可行的:

.circle { 边框:0.1em纯灰色; 这个特性:100%; 高度:2 em; 宽:2 em; text-align:中心; ｝ .circle p { margin-top: 0.10 em; 字体大小:1.5 em; 粗细:大胆的; 字体类型:无衬线; 颜色:灰色; ｝ 身体< > < div class = "圆" > < p > < / p > 30 < / div > 身体< / >
