+`<core-transition-css>` implements CSS transitions as `<core-transition>` objects so they can be |
+reused in a pluggable transition system such as in `<core-overlay>`. Currently this class has |
+some specific support to animate an element from and to the viewport such as a dialog, but you |
+can override it for different effects. |
+ |
+Example: |
+ |
+my-css-transition.html: |
+ |
+ <polymer-element name="my-css-transition" extends="core-transition-css"> |
+ <template> |
+ <style> |
+ :host(.my-transition) { |
+ opacity: 0; |
+ transition: transform 1s ease-out, opacity 1s ease-out; |
+ } |
+ :host(.my-transition.my-opened) { |
+ opacity: 1; |
+ transform: none; |
+ } |
+ :host(.my-transition-top) { |
+ transform: translateY(-100vh); |
+ } |
+ :host(.my-transition-bottom) { |
+ transform: translateY(100vh); |
+ } |
+ </style> |
+ </template> |
+ <script> |
+ Polymer({ |
+ baseClass: 'my-transition', |
+ openedClass: 'my-opened' |
+ }); |
+ </script> |
+ </polymer-element> |
+ |
+ <my-css-transition id="my-transition-top" transitionType="top"></my-css-transition> |
+ <my-css-transition id="my-transition-bottom" transitionType="bottom"></my-css-transition> |
+ |
+my-css-transition-demo.html |
+ |
+ <link href="components/core-meta/core-meta.html" rel="import"> |
+ <link href="my-css-transition.html"> |
+ |
+ <div id="animate-me"></div> |
+ |
+ <script> |
+ // Get the core-transition |
+ var meta = document.createElement('core-meta'); |
+ meta.type = 'transition'; |
+ var transition1 = meta.byId('my-transition-top'); |
+ |
+ // Set up the animation |
+ var animated = document.getElementById('animate-me'); |
+ transition1.setup(animated); |
+ transition1.go(animated, {opened: true}); |
+ </script> |
+ |
+The first element in the template of a `<core-transition-css>` object should be a stylesheet. It |
+will be injected to the scope of the animated node in the `setup` function. The node is initially |
+invisible with `opacity: 0`, and you can transition it to an "opened" state by passing |
+`{opened: true}` to the `go` function. |
+ |
+All nodes being animated will get the class `my-transition` added in the `setup` function. |
+Additionally, the class `my-transition-<transitionType>` will be applied. You can use the |
+`transitionType` attribute to implement several different behaviors with the same |
+`<core-transition-css>` object. In the above example, `<my-css-transition>` implements both |
+sliding the node from the top of the viewport and from the bottom of the viewport. |
+ |
+Available transitions |
+--------------------- |
+ |
+`<core-transition-css>` includes several commonly used transitions. |
+ |
+`core-transition-fade`: Animates from `opacity: 0` to `opacity: 1` when it opens. |
+ |
+`core-transition-center`: Zooms the node into the final size. |
+ |
+`core-transition-top`: Slides the node into the final position from the top. |
+ |
+`core-transition-bottom`: Slides the node into the final position from the bottom. |
+ |
+`core-transition-left`: Slides the node into the final position from the left. |
+ |
+`core-transition-right`: Slides the node into the final position from the right. |
