将字体真棒跨度图标放置在锚点内的文本上方

【中文标题】将字体真棒跨度图标放置在锚点内的文本上方

【英文标题】：Position font awesome span icon above text within an anchor

【发布时间】：2017-09-29 19:17:43

【问题描述】：

我正在尝试制作一些按钮，其文本位于字体真棒图标下方，两者都位于列表项的中心位置，我需要锚元素，它还包含字体真棒图标的 span 元素，以填充列表项的整个大小。

我可以用锚点填充列表项没有问题，但是我无法将图标的跨度定位在包含它的锚点中的文本上方。

【参考方案2】：

问题来自flex。我建议将另一个 div 包裹在应该在 a 标签内居中的元素周围

【参考方案3】：

只需将position: absolute; top: 40px; 添加到字体很棒的图标中
