一个真正好的用户界面设计应该是不被用户注意到的UI设计；相反，贫庸的界面设计往往强制用户去注意到自己的设计痕迹，而不是内容本身。用户访问一个网站的目的无非是实现自己的目标：买一本书、学些一下jQuery、分享一篇文章、寻找一段音乐、写一篇小说等等。用户不是来把玩你的设计的，实际上用户基本不关心你的设计。一直以来pc的死板以及一些缺乏交互的软件让我们思考用户界面的问题，什么能让界面设计变好，什么又能使之变坏，但是我们真的有必要让我们的用户也关注这些东西吗？精心开发5年的UI前端框架！
网页设计师们花了成千上万的时间在按钮的颜色、阴影、边框、渐变等这些常用的设计元素上面，让自己的界面看起来更好用，更舒服，但是用户界面设计的终极挑战不在于吸引眼球，而在于不留痕迹，雁过无声，踏雪无痕。
If you haven’t heard, mobile devices are kind of a big deal these days. The multi-touch device has cracked open the idea that user interfaces are a series of clicks and sequences that allow manipulation of content — mobile devices allow more natural user interaction
between the human and the content embedded on the device. These Natural User Interfaces (NUI) are more “natural” for a variety of reasons, but, direct
manipulation of content and the lack of antiquated
metaphors (the desktop) allow these devices to be super easy to use because their interfaces are almost invisible.精心开发5年的UI前端框架！
But we still work on desktop and laptop computers, we still view web sites and use web applications that can’t always take advantage of this new, more natural interface design with all the wonderful multi-touchy stuff that makes these devices so much fun to
use. So, because we aren’t quite there yet, do we continue to create old, “get in the way” interface components? We shouldn’t. The goal of an invisible interface should be the goal of every UI designer and developer.
