它已经演变成我分享包含SVG文档的Markdown文本的理想工具。鉴于我

in your browser and paste in some Markdown to see it rendered… or save that Markdown to a CORS-friendly URL or a GitHub Gist and paste in a URL to that document.
并粘贴一些Markdown即可查看渲染效果……或者将Markdown保存到支持CORS的URL或GitHub Gist，然后粘贴该文档的URL。
The URL option will give you a bookmarkable page, for example
URL选项会给你一个可加书签的页面，例如

As you can see, that SVG block in the Markdown has been transformed into a rendered SVG (in this case animated) plus several tabs.
如你所见，Markdown中的那个SVG块已被转换为渲染后的SVG（在这个例子中是动画），外加几个标签页。
The tabs are the really fun bit. The PNG and JPEG tabs render that SVG to those image formats in the browser and lets you copy or download them - useful for sharing on platforms that don’t support SVG directly.
标签页才是真正有趣的部分。PNG和JPEG标签页会在浏览器中把SVG渲染为这些图像格式，并允许你复制或下载它们——这对于在不直接支持SVG的平台上分享非常有用。

so it can compile those frames into an MP4 video using the full power of FFMPEG compiled to WebAssembly and running in the browser.
以便利用编译为WebAssembly并在浏览器中运行的FFMPEG的全部功能，将这些帧编译成MP4视频。
Being able to turn an animated SVG into a MP4 again makes it easy to share on platforms that can’t support SVG animation natively. It’s a neat trick!
能够将动画SVG再转成MP4，使得在不原生支持SVG动画的平台上分享变得容易。这是个巧妙的技巧！
