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?

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>

你可以使用border-radius:

<html>
  <head>
    <style type="text/css">

    .round
    {
        -moz-border-radius: 15px;
        border-radius: 15px;
        padding: 5px;
        border: 1px solid #000;
    }

  </style>
  </head>  
  <body>   
    <span class="round">30</span>
  </body>
</html>  

调整边界半径和填充值,直到你对结果满意为止。

但这并不适用于所有浏览器。我猜IE仍然不支持圆角。

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>

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> .

这个版本不依赖于硬编码的固定值,而是相对于div的字体大小。

CSS:

.numberCircle {
    font: 32px Arial, sans-serif;

    width: 2em;
    height: 2em;
    box-sizing: initial;

    background: #fff;
    border: 0.1em solid #666;
    color: #666;
    text-align: center;
    border-radius: 50%;    

    line-height: 2em;
    box-sizing: content-box;   
}

HTML:

<div class="numberCircle">30</div>
<div class="numberCircle" style="font-size: 60px">1</div>
<div class="numberCircle" style="font-size: 12px">2</div>

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;
}
