Question

Is it possible to have a css transition that fades an element in on hover but simply hides the element when the mouse leaves.

i.e. hover in = fade for 0.5 seconds | hover out = no fade and instant

Answer 1

Yes, you can achieve this using CSS3 transitions. Essentially, your CSS should look like this:

#myLink {
    opacity: 0;
}

#myLink:hover {
    opacity: 1;
    -webkit-transition: all 0.2s ease-in-out;
    -moz-transition: all 0.2s ease-in-out;
    -o-transition: all 0.2s ease-in-out;
    transition: all 0.2s ease-in-out;
}

And here’s a jsFiddle to demonstrate: Fiddle
