html - 如何随着增加圆圈内的文字而增加一个圆圈？

Question

我想在圆圈内放置文字。是否可以在文字增加的时候动态增加圆圈的大小？
This is an example .
但在这个例子中我遇到的问题是只有宽度随文本增加。

例如

.badge {
    background:             radial-gradient( 5px -9px, circle, white 8%, red 26px );
        background:    -moz-radial-gradient( 5px -9px, circle, white 8%, red 26px );
        background:     -ms-radial-gradient( 5px -9px, circle, white 8%, red 26px );
        background:      -o-radial-gradient( 5px -9px, circle, white 8%, red 26px );
        background: -webkit-radial-gradient( 5px -9px, circle, white 8%, red 26px );
    background-color: red;
    border: 2px solid white;
    border-radius: 12px; /* one half of ( (border * 2) + height + padding ) */
    box-shadow: 1px 1px 1px black;
    color: white;
    font: bold 15px/13px Helvetica, Verdana, Tahoma;
    height: 16px; 
    padding: 4px 3px 0 3px;
    text-align: center;
    min-width: 14px;
}

/* only needed for this sample */
.badge {
    float: left;
    left: 25px;
    margin: 6px;
    position: relative;
    top: 25px; 
}

<div class="badge">1</div>
<div class="badge">2</div>
<div class="badge">3</div>
<div class="badge">44</div>
<div class="badge">55</div>
<div class="badge">666</div>
<div class="badge">777</div>
<div class="badge">8888</div>
<div class="badge">9999</div>

我认为您需要使用 javascript 来调整高度以匹配宽度；您还应该使用 50% 作为边界半径。我修改了your example .

$(document).ready(function(){$('.badge').each(function(){
    $(this).height($(this).width());
    $(this).css('line-height', $(this).height()+'px');
})});

.badge {
    background:             radial-gradient( 5px -9px, circle, white 8%, red 26px );
        background:    -moz-radial-gradient( 5px -9px, circle, white 8%, red 26px );
        background:     -ms-radial-gradient( 5px -9px, circle, white 8%, red 26px );
        background:      -o-radial-gradient( 5px -9px, circle, white 8%, red 26px );
        background: -webkit-radial-gradient( 5px -9px, circle, white 8%, red 26px );
    background-color: red;
    border: 2px solid white;
    border-radius: 50%; /* one half of ( (border * 2) + height + padding ) */
    box-shadow: 1px 1px 1px black;
    color: white;
    font: bold 15px/13px Helvetica, Verdana, Tahoma;
    height: 16px; 
    padding: 3px;
    text-align: center;
    min-width: 16px;
}

.badge {
    float: left;
    left: 25px;
    margin: 6px;
