html - Markdown 中的 Span 元素

Question

我用下面几行代码写了一个markdown.md。

<span style="font-family: Open Sans; font-weight: 300; font-size: 16px; font-style: normal">300 Light normal hamburgefonstiv</span>
<br /> <span style="font-family: Open Sans; font-weight: 300; font-size: 16px;font-style: italic">300 Light italic hamburgefonstiv</span>
<br /> <span style="font-family: Open Sans; font-weight: 400; font-size: 16px; font-style: normal">400 Regular normal hamburgefonstiv</span>
<br /> <span style="font-family: Open Sans; font-weight: 400; font-size: 16px;font-style: italic">400 Regular italic hamburgefonstiv</span>
<br /> <span style="font-family: Open Sans; font-weight: 600; font-size: 16px; font-style: normal">600 Semibold normal hamburgefonstiv</span>
<br /> <span style="font-family: Open Sans; font-weight: 600; font-size: 16px;font-style: italic">600 Semibold italic hamburgefonstiv</span>
<br /> <span style="font-family: Open Sans; font-weight: 700; font-size: 16px; font-style: normal">700 Bold normal hamburgefonstiv</span>
<br /> <span style="font-family: Open Sans; font-weight: 700; font-size: 16px;font-style: italic">700 Bold italic hamburgefonstiv</span>
<br /> <span style="font-family: Open Sans; font-weight: 800; font-size: 16px; font-style: normal">800 ExtraBold normal hamburgefonstiv</span>
<br /> <span style="font-family: Open Sans; font-weight: 800; font-size: 16px;font-style: italic">800 ExtraBold italic hamburgefonstiv</span>

当我打开浏览器时，我看到了这个。它工作正常。当我在 Github 上打开 markdown.md 时，我只看到文本行作为普通文本。怎么了？带有 span 元素的想法是否正确？

虽然GitHub的markdown规范支持some HTML , 目前完全不支持 CSS。参见 here :

GitHub strips style tags and attributes preventing you from changing the style on their pages. This is probably for security reasons. If you could inject css into GitHub pages, you could easily launch a phishing attack.
