Html 转换时间不适用于CSS3

我正在制作一个有完整背景图片转换的网站。 问题是动画，我不能让它们正常工作。我希望它们能从一个图像淡入另一个图像，而不会在图像之间出现黑屏。这是我的现场网站：

我尝试了很多方法，但我无法解决这个问题，即使是在试图改变时间的时候

有人知道如何解决这个问题吗？ 这是我目前的代码：

HTML:

天哪。。谢谢你，伙计！我头痛，因为我无法解决这个问题=D测试链路工作正常。你可以看看，testes-cmt.bl.ee再次感谢。对不起，我不能给你一个+代表，因为我只有不到15个。太好了，很高兴它能工作。这是一个非常巧妙的纯CSS幻灯片，你正在使用。是的，我知道有一些JS等，但我想保持我的网站所有的HTML和CSS，除了倒计时我想放。但是仍然找不到一个很好的教程。我是新的先进技术，建立一个专业的网页设计师。
