初学前端请教一个问题：由内容撑开的块级元素如何居中？

这是一个创建于 4436 天前的主题，其中的信息可能已经有所发展或是发生改变。

今天要写一个图片幻灯，图片下方居中位置有几个圆点来作为切换图的TAB。
圆点数量是要随图片张数变的，所以不能用固定宽度margin auto来做，圆点是CSS写的，所以不能转成行级用text-align。
请问该如何做？不用JS

原点外面包个 div，然后在这个 div 上写 CSS：text-align: center;

<!Doctype html>
<meta charset="UTF-8">
<style>
p { text-align: center; }
i { background-color: #f90; font-size: 12px; cursor: pointer; padding: 2px 6px; border-radius: 12px; overflow: hidden; box-shadow: inset 0 9px 9px rgba(255, 255, 255, .2); }
</style>

@kfll 原来如此，之前一直用固定高宽，一变inline就瘪了。。。原来可以用空格+padding撑开行级元素。。就是有点不好算高宽
