Fragments in reveal.js using Markdown
提问by Uwe L. Korn
reveal.js supports fragments which will be shown one after another in HTML
reveal.js 支持在 HTML 中一个接一个显示的片段
<section>
<p class="fragment grow">grow</p>
<p class="fragment shrink">shrink</p>
<p class="fragment roll-in">roll-in</p>
<p class="fragment fade-out">fade-out</p>
<p class="fragment highlight-red">highlight-red</p>
<p class="fragment highlight-green">highlight-green</p>
<p class="fragment highlight-blue">highlight-blue</p>
</section>
It supports using MarkDown instead of HTML for each slide using:
它支持使用 MarkDown 而不是 HTML 为每张幻灯片使用：
<section data-markdown>
## Page title
A paragraph with some text and a [link](http://hakim.se).
</section>
But I could not find any documentation on using fragments using MarkDown. Did I miss something or is it not yet supported?
但是我找不到任何关于使用 MarkDown 使用片段的文档。我错过了什么还是它不支持？

It support attributes now, by adding tag: <!-- .element: class="fragment" -->.
它现在支持属性，通过添加标签：<!-- .element: class="fragment" -->。
There are more attributes supported such as background, index, etc. See more examples on official doc: Element Attributes, Slide Attributes.

If you are looking to create fragments inside a markdown formatted section as jez pointed out in his comment, this is what you need
如果您想在 jez 在评论中指出的降价格式部分中创建片段，这就是您所需要的
* Item 1 <!-- .element: class="fragment" -->
* Item 2 <!-- .element: class="fragment" -->

Please refer this issue Markdown inside fragments, and I think the fragment only applies in html level.
请参考此问题Markdown inside fragment，我认为该片段仅适用于 html 级别。
I think you may manipulate the dom after markdown transformed directly, just like this -
我觉得你可以直接操作markdown转化后的dom，就像这样——
{ src: 'plugin/markdown/markdown.js',
condition: function() { return !!document.querySelector( '[data-markdown]' ); },
callback: function() {
Array.prototype.forEach.call(document.querySelectorAll('section > p'), function(ele){ ele.className = 'fragment'; });
}
},
