Nash Vail has a passion for designing building user interfaces. He is currently a Computer Science undergrad and actively looking for internship opportunities. He has his own little blog you should check out, you can find him on Twitter, GitHub, Dribbble or shoot him a mail at hello@nashvail.me.
There is UI animation, and then there is good UI animation. Good animation makes you go “Wow!” — it’s smooth, beautiful and, most of all, natural, not blocky, rigid or robotic. If you frequent Dribbble or UpLabs, you’ll know what I am talking about.

Now, CSS does provide some presets for transition-timing-function, such as ease-in, ease-out and ease-in-out, which add some level of smoothness and realism, but they are very generic, aren’t they?

That definitely requires a significant amount of learning, but isn’t that what we developers do and should be good at? Quickly learn new languages and frameworks? What’s the point, then? For me, the advantages never outweighed the doubts.
