use*_*068 8 html css shadow-dom polymer
首先,我很难理解Polymer中英雄转型的基本原理.我正在尝试构建一个类似于他们提供的示例中的英雄过渡卡,可以在此处找到.下面我已经制作了迷你卡,我只是想了解过渡以及较大的卡如何与较小的卡一起工作.
我的具体问题是,转换如何绑定到每个元素?在开始使用核心动画页面之前,我是否需要完成两者的CSS?嵌入式模板是否重要?
任何指导都会非常有帮助.

实际上,您已经非常接近现有代码的工作转换。
我在我的网站上实现了一个更复杂的英雄转换,并从那里获取了一些代码来让你的网站工作。
<core-animated-pages transitions="hero-transition" selected={{page}}>
<section>
<paper-shadow z="1" id='paper_shadow' on-mouseover="{{raise}}" on-mouseout="{{lower}}" hero-p on-tap="{{transition}}">
<div id="chip_body" hero-id="chip_body" hero vertical layout center justified>
<div id="chip_top" flex>
<div id="coreImage">
<content select="#core-image"></content>
</div>
</div>
<div id="chip_bottom" vertical layout start-justified>
<div id='text'>
<content select="#chip_bottom"></content>
</div>

</div>

<section id="page2">
<div id="card_container" hero-id="chip_body" on-tap="{{transition}}" hero></div>

我只做了一些调整。
hero-p属性的英雄父元素都应该只包含该属性。所以不需要引号:)<paper-shadow hero-p .. >hero属性。<div id="chip_body" .. hero .. > <div id="card_container" .. hero .. >我已将您的代码的工作版本放在我的网站上。
有一个页面包含该<chip-card>元素,第二个页面包含工作模板文件。
请注意:我编辑了参考以webcomponentsjs符合我的文件夹结构。
还有什么事情就尽管问我吧!
