将罗马数字样式应用于计数器输出
CSS
body {
counter-reset: item-counter;
}
.item {
counter-increment: item-counter;
}
.item:before {
content: counter(item-counter, upper-roman) ". "; /* by specifying the upper-roman as style the output would be in roman numbers */
}
HTML
<div class='item'>Item No: 1</div>
<div class='item'>Item No: 2</div>
<div class='item'>Item No: 3</div>
在上面的例子中,计数器的输出将显示为 I,II,III(罗马数字),而不是通常的 1,2,3,因为开发人员明确指定了计数器的样式。
