103 `cascade-transition` slides the children of a container up in sequence, creating
a | |
104 reverse waterfall effect. It works well with both grids and lists. Configure the | |
105 duration of the transition with the global variable `CoreStyle.g.transitions.cas
cadeDuration`. | |
106 | |
107 Example: | |
108 | |
109 <core-animated-pages transition="cascade-transition"> | |
110 <section> | |
111 <div id="container" cascade> | |
112 <div>item 1</div> | |
113 <div>item 2</div> | |
114 <div>item 3</div> | |
115 <div>item 4</div> | |
116 <div>item 5</div> | |
117 <div>item 6</div> | |
118 <div>item 7</div> | |
119 </div> | |
120 </section> | |
121 <section></section> | |
122 </core-animated-pages> | |
123 | |
124 In the above example, the immediate children of `#container` will slide up in | |
125 sequence when the page transitions from 0 to 1. | |
126 | |
127 The items can optionally fade in as they slide. Add the `fade` attribute to | |
128 the container to do that and configure the duration of the opacity transition wi
th | |
129 the global variable `CoreStyle.g.transitions.cascadeFadeDuration`. | |
