Hello, On this website when mouse comes on the image, links are displaying and image is going darker. how can i do this? http://tinyurl.com/y9mu4qu thanks
This seems to be done with JavaScript, not CSS, since the darker overlay in fading in/out. I'd suggest looking into jQuery. There are several ways of doing this, but you'll most likely be looking at the "hover" event.
The feature of site you showed is completely built in CSS and Jquery. Nothing to do with the php. Please post the thread in CSS or jquery categories.
