Reply To: image fade on rollover

Take a look for this in your css (its around line 177 in the demo) –

a,
button,
input[type="button"],
input[type="reset"],
input[type="submit"] {
	-webkit-transition: all 0.1s ease-in-out;
	-moz-transition:    all 0.1s ease-in-out;
	-ms-transition:     all 0.1s ease-in-out;
	-o-transition:      all 0.1s ease-in-out;
	transition:         all 0.1s ease-in-out;
}<!--formatted-->

It’s set at the lowest speed, but you can increase it if you want to use it.
