How to use CSS to surround a number with a circle?-第2页回答

My solution here - this easily allows for different sizes and colors and ties into a CMS for editorial control. For IE degrading to squares.

HTML:

<div class="circular-label label-outer label-size-large label-color-pink">
    <div class="label-inner"> 
        <span>Fashion & Beauty</span>
    </div>
</div>

CSS:

.circular-label {
    overflow: hidden;
    z-index: 100;
    vertical-align: middle;
    font-size: 11px;
    -webkit-box-shadow:0 3px 3px rgba(0, 0, 0, 0.2);
    -moz-box-shadow:0 3px 3px rgba(0, 0, 0, 0.2);
    box-shadow: 3px 3px 3px rgba(0, 0, 0, 0.2);
}
.label-inner {
    width: 85%;
    height: 85%;
    -moz-border-radius: 50%;
    -webkit-border-radius: 50%;
    border-radius: 50%;
    border: 2px dotted white;
    vertical-align: middle;
    margin: auto;
    top: 5%;
    position: relative;
    overflow: hidden;
}
.label-inner > span {
    display: table;
    text-align: center;
    vertical-align: middle;
    font-weight: bold;
    text-transform: uppercase;
    width: 100%;
    position: absolute;
    margin: auto;
    margin-top: 38%;
    font-family:'ProximaNovaLtSemibold';
    font-size: 13px;
    line-height: 1.0em;
}
.circular-label.label-size-large {
    width: 110px;
    height: 110px;
    -moz-border-radius: 55px;
    -webkit-border-radius: 55px;
    border-radius: 55px;
    margin-top:-55px;
}
.circular-label.label-size-med {
    width: 76px;
    height: 76px;
    -moz-border-radius: 38px;
    -webkit-border-radius: 38px;
    border-radius: 38px;
    margin-top:-38px;
}
.circular-label.label-size-med .label-inner > span {
    margin-top: 33%;
}
.circular-label.label-size-small {
    width: 66px;
    height: 66px;
    -moz-border-radius: 33px;
    -webkit-border-radius: 33px;
    border-radius: 33px;
    margin-top:-33px;
}

It's not too difficult to see how to do this. The bigger question is whether it is possible to make the dimensions of the circle scale to content.

Currently I don't think it is possible. Anyone?

Something like what I've done here could work (for numbers 0 to 99):

CSS:

.circle {
    border: 0.1em solid grey;
    border-radius: 100%;
    height: 2em;
    width: 2em;
    text-align: center;
}

.circle p {
    margin-top: 0.10em;
    font-size: 1.5em;
    font-weight: bold;
    font-family: sans-serif;
    color: grey;
}

HTML:

<body>
    <div class="circle"><p>30</p></div>
</body>

Heres my way of doing it, using square method. upside is it works with different values, but you need 2 spans.

.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>

You can use the border-radius for this:

<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>

Play with the border radius and the padding values until you are satisfied with the result.

But this won't work in all browsers. I guess IE still does not support rounded corners.

For circle sizes varying based on the content this should work:

http://jsfiddle.net/nzsnw55s/

<span class="numberCircle"><span>30</span></span>
<span class="numberCircle"><span>1</span></span>
<span class="numberCircle"><span>5435</span></span>
<span class="numberCircle"><span>2</span></span>
<span class="numberCircle"><span>100</span></span>

.numberCircle {
  display:inline-block;
  line-height:0px;

  border-radius:50%;
  border:2px solid;

  font-size:32px;
}

.numberCircle span {
  display:inline-block;

  padding-top:50%;
  padding-bottom:50%;

  margin-left:8px;
  margin-right:8px;
}

It relies on the width of the content plus the margin-'s to determine the radius, then extends the height to match using the padding-'s. The margin-'s would need to be adjusted based on the font-size.

Update to remove inner element:

<span class="numberCircle">30</span>
<span class="numberCircle">1</span>
<span class="numberCircle">5435</span>
<span class="numberCircle">2</span>
<span class="numberCircle">100</span>

<style type="text/css">
.numberCircle {
    display:inline-block;

    border-radius:50%;
    border:2px solid;

    font-size:32px;
}

.numberCircle:before,
.numberCircle:after {
    content:'\200B';
    display:inline-block;
    line-height:0px;

    padding-top:50%;
    padding-bottom:50%;
}

.numberCircle:before {
    padding-left:8px;
}
.numberCircle:after {
    padding-right:8px;
}
</style>

Uses pseudo-elements to force the height. Need the zero width space for vertical alignment. Moved the line-height:0px from the outer to the pseudo so that it is at least visible when degrading for IE8.

Improving the first answer just get rid of the padding and add line-height and 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;
}
