I have created an image gallery and every time I hover over one I want a white overlay to show that the image is being hovered on however I would not want to lose the quality of the image.I have already tried changing the opacity but I want it to start with a 100% opacity and then increase.However, this is not possible so I would like a highlight over the image without decreasing the quality.

Why is this happening? do I need css to change the opacity or can I just use the image.

CSS3 Opacity issue

Here is the project site: Site Redesign.
What I'm trying to do is keep the backgrounds for each section to be at the 0.5-0.7 opacity, but the text in all the content at 1.0
I've tried making a class 'text' with opacity 1.0 but that doesnt do anything, and I don't want to lose the opacity currently there.
I believe your answer is here: CSS opacity only to background color not the text on it?.
You want to specify the transparent background with the background property.
