There is the simplest animation:
@-webkit-keyframes port { from {opacity: 0;} to {opacity: 1;} } .port:hover .port_inf {-webkit-animation:port 1s;}
When we point at .port, we see .port_inf smoothly, but when we move the cursor away, the block disappears abruptly. And you need to make it also smoothly disappear. How to do it?
Thank you in advance!
