| `<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. |
