I'm currently messing around with impress.js, and I couldn't help but notice that some divs or images, when put through the css of impress.js, turn see-through -- not trasparent, only see-through. For example, in this fiddle, the first two images are see-through, while the other two are completely opaque.
What I don't want is those two images to go see-through like that. I cannot understand what is causing only those two to be like that, while the others are in an opposite state. I tried using different pictures, inter-changing places of the pictures, changing and scaling the elements, but they don't seem to work. Although changing the 7th line in the css to opacity: 1; does help, but it fails to give the desired effect on the elements that are not active, which is kind of important.
If anybody with a higher knowledge than mine (I'm an idiot in these matters, by the way) could look into this, their help will be highly appreciated.
Thanks in advance.
