javascript - Div 走出屏幕

Question

我正在尝试结合这两个脚本:

• > http://designmodo.com/video-background-website/
• > http://www.jqueryscript.net/time-clock/Modern-Circular-jQuery-Countdown-Timer-Plugin-Final-Countdown.html

但是我有一个问题。在笔记本电脑上一切看起来都很好，但是当我将窗口调整为平板电脑/手机尺寸时，计数器正在屏幕上方移动。我整天都在玩不同的 css 设置，但无法弄清楚:(

演示: http://brandflow.pl/products/bootstrap/flow%20coming%20soon/video%20+%20round/

我认为这与处理视频的 DIV 的位置有关...

Answer 1

这个:.countdown-container 有这个:

-webkit-transform: translateY(-50%);
-moz-transform: translateY(-50%);
转换:translateY(-50%);

一组属性。

页面还有其他问题，但对于那个特定的问题，您应该调整或删除它们。
