【问题描述】:
我正在尝试找出如何强制元素从底部开始到顶部。
我已经通过 stackoverflow 进行了搜索,但我似乎无法得到我需要的答案。 这张图应该能解释清楚:
这也应该有帮助:

【问题讨论】:
-
这是一个有趣的问题。我很确定这是不可能的。为什么不能以相反的顺序插入元素? (不改变html中的顺序)
-
您应该始终在问题中包含相关代码。这样,如果您链接的文件/页面不复存在,您的问题仍然存在,并且将来可能对其他人有用。
-
我的错,我在插入代码时遇到了问题。但是,是的,我会记住这一点。谢谢,詹姆斯蒙塔涅。

@Oliver 啊,因为我需要元素按那个顺序排列。我正在做的实际上是关于一个班级出勤检查网站。底部是第一行,顶部是第二行。我需要模拟一下,当老师在教室前面检查出勤座位时,他/她会如何看待它。
