If you apply a transition on an element for a particular supported property, and that property ever changes, it will use that transition. If a class name on that element changes and the new class changes that property, it will transition (assuming what that class does isn't remove the transition). If JavaScript literally changes the that style property, it will transition.

Likewise, if a new media query takes affect, and that media query has something in it that changes that property on that element, it will transition. As such, there really isn't a such thing as an "animated media query" so much as elements that just transition as expected when a new media query starts affecting the page.

Minimize HTTP Requests

80% of the end-user response time is spent on the front-end. Most of this time is tied up in downloading all the components in the page: images, stylesheets, scripts, Flash, etc. Reducing the number of components in turn reduces the number of HTTP requests required to render the page. This is the key to faster pages.

Joseph上次 JSDC 講「F2E, the Keystone」 獲得不差的迴響，受上官大大的邀請到微軟 TechDay 2013 再分享一堂。但聽眾族群完全不一樣 ( Modern Developer / Enterprise Developer )，所以多花了不少時間重新編排投影片，也找到許多我第一份工作、在企業內打拼的有趣回憶。不過重點還是延續 JSDC 的目標：讓前端真的成為一個產業。若企業也能一起導入像是 User Experience (使用者體驗) 及前端工程的話，我們做出來的東西才真的會有國際競爭力（尤其針對在做像是 Accouting, CRM, ERP, Portal, Workflow... 服務的那些公司）。

A central feature of Twitter Bootstrap 3 is the use of modern flat UI design that has become so popular.  If you want to see what kind fo Bootstrap 3 designs have been created, here are some early examples of what can be done with this new framework. Be ware that most of these examples are very early testing of Bootstrap 3 so they might not be as complete as Bootstrap 2. If you are already using Bootstrap 2, then switching over to Bootstrap 3 should not be an issue.
