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?

在css中做这样的事情吗
div {
width: 10em; height: 10em;
-webkit-border-radius: 5em; -moz-border-radius: 5em;
}
p {
text-align: center; margin-top: 4.5em;
}
使用段落标签来书写文本。希望这能有所帮助

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>
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>
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。
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。
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>
