他們使用CSS3過渡效果DEMO http://jsfiddle.net/kevinPHPkevin/xejsM/500/
a {
color:blue;
/* First we need to help some browsers along for this to work.
Just because a vendor prefix is there, doesn't mean it will
work in a browser made by that vendor either, it's just for
future-proofing purposes I guess. */
-o-transition:color .2s ease-out, background 2s ease-in;
-ms-transition:color .2s ease-out, background 2s ease-in;
-moz-transition:color .2s ease-out, background 2s ease-in;
-webkit-transition:color .2s ease-out, background 2s ease-in;
/* ...and now for the proper property */
transition:color .2s ease-out, background 2s ease-in;
}
對,我們現在覺得自己很傻。謝謝! – Crashalot
